Fuel consumption / economy report

[boggy2006]

hi,

thought it might be a useful reference if I posted my fuel consumption figures. Feel free to add yours as well, including vehicle details and road conditions;

1992 GQ Patrol LWB, auto, LPG.
This is basically my commuting run below;
35% highway, continuous stop/start at traffic lights with fairly brisk acceleration keeping up with other traffic
60% freeway, crawling through 20km of very heavy traffic and congestion, continous stops and slow driving.
5% freeway at 100kph (yep the last 5% of my journey is not congested!!)
This week it used 26.8l/100km of LPG. But with the Safeway discount it still only cost 48c/l, so about 40 bucks. Still not bad.

[89GQ]

NA TD42, 300.000 k's around town about 14L/100Ks, Highway 11-12L/100Ks. Getting much better economy by remooving pre-air cleaner and adding 2 stroke 200:1.

[AB]

Moved your thread here mate so others can see it better.

[Bigrig]

92 GQ TB42e running LPG (dual, but run LPG where possible)

Around town - 30 ltr's/100 klms
Open Freeway - 24-25 ltr's/100 klms
Downhill, with a tailwind, in the slip stream of a truck - 18-20 ltr's/100 klms ... only problem with this concept so far is I haven't found a hill, a tailwiind nor a truck that goes for 100 klms to keep my consumption down!!! lmfao ...

thats the prob with driving to Melbourne - you have to come back....

I have a TB42E as well
Around town - 30 ltr's/100 klms
Open Freeway - 20-21 ltr's/100 klms

But have a dodgy valve - head getting done soon so will post new figures when done.

Being an oily man things are different.
My '89 td42 when I bought it at 120K about 15 years ago was damn near 10l/100 or in proper terms 100K/10 L. or forgetting this new B/S**t near 28 or so M.P.G.. Never had the injectors replaced et. and it went slowly downhill till it got to a bit under 12L/100. after 400K. At that stage a good long trip with a 2T. van on the back cleaned things out and it improved till we got back to bloody shopping trips again.
Being the son of a tight a**e man I do drive with my mind on juice and brake pads so keeping up with mad a**se traffic hasn't really been a concern.
Got a feeling that my new zd30 turbo may be a whole new learning experience though.
Would love to hear what rev. range gives best economy/performance with and without a van though. Any thoughts?

[Bob]

I have a 1998 4.5 L GU (Dual Fuel) and on a recent trip to Melbourne through to Dandenong from Bendigo and mostly on Freeway I filled up at Calder Raceway on the way home. Required 47 Litres of Gas and I had covered 250 K's. That equates to 18.8 Litres per 100 K's.

[big_fletch]

I have a 2002 Gu III patrol, 3.0 Turbo Diesel, Manual. Also running Manual boost, blocked EGR ect....
I average around 10 litres to 100km's on a highway, thats sitting on 100km/h.. Sits around 10-12psi boost and 260-300 on the pyro
Around town i get around 12 or so litres to 100km's. Boost and temps vary depending on how heavy my right foot is that day haha

Thats not to bad i dont reckon

Ahhhh ... I feel better all of a sudden!! lmfao ... sorry mate, had to take the opportunity. What sort of trip (i.e. large portion at 100klms per hour?) - mine uses about 30 litres per 100 around town, but drops (not sure on petrol though) to about 22-23 per 100 on the open road ... I suspect you're spot on the money and something isn't quite right ...

[boggy2006]

Update:
on my usual weekly commuter run, my fuel consumption dropped from 26l to 18l/100km. Why???? The only thing I did was inflate the tyres! A couple were a bit low, about 15-20psi (I just bought the car and it's the first time I checked), so they are all up to 30psi now. Could that make such a difference?

On another run at the weekend, mainly 100kph for 2 hours and some slow driving/rought roads for 1 hour, I got 20l/100km.

(both with a/c on most of the time).

[MudRunnerTD]

On my trip up through Central Oz (6000kms) towing the camper my GU IV TD42Ti I averaged 17lt/100 going up the middle on the bitumen, was out to about 24lt/100 on the dirt in 4wd.

I just did a check yesterday running down the hwy and commuting about the place and i got 14.2lt/100kms and very very pleased with that.

Awesome consumption figures mate - I'm never going to get the rig down to those sort of numbers, but even around 20 (or just below) on the open road fully UNLADEN would be a bonus :frown:!!!

[boggy2006]

those diesels sure are good on fuel. But when I fill up with LPG at 48c/l (56c-8c discount) I love it! Mind you I am from the UK where petrol was at least $2.60/l !!! So it costs me the same to run my Patrol as a small 1.6l diesel car would in the UK.

[Baileys]

Hi, Just reading this info about your fuel consumption and thought I might put it out there also.
Has anyone had any experiences with installing a hydrogen set up in there patrol? I was talking to a guy who has an old Mav and he bought it with this already installed and he swears by it. He has more power, less emmission and better fuel consumption. It basically consists of a jar with about 75% full of de-mineralised water or rain water that is charged, producing hydrogen gas that is sucked into the fuel system or manifold???. He said he can not produce enough hydrogen. All he does is top it up once a week.
I would like to investigate this to see if this can in fact be fitted and is as good as it sounds.
Any ideas?
Oh - and my 94 GQ gets 13Ks/100Ltrs...
Baileys - Coffs Harbour, NSW.

I mean 13ltrs/100Klms...DUH

[Nanango]

For those interested in straight petrol fuel figures, I will be doing a 1500Km run in a EFI 4.2 (TB42E) 96 patrol next week and plan on keeping a close eye on the consumption figures. No towing, roof rack, and 95% of distance as highway miles. Will post the results towards the end of next week. I'm certainly hopeing they work out fairly good.

[v.t.c 4800]

my gu tb48
with 1 tank can move around 400 km

[Nanango]

Sorry, forgot, it is a GQ, those are the figures I have been told to expect. Just bought the car, and looking foward to see exactly what I can get with careful driving.

Hey Hey, i got my mathes wrong a little. Those figures for current would be accurate if i had standard tyres...But i have 285's on and that put my speedo out 6%. Soooo..wait for it...6% adjustment..???

My TD42Tdi just got 13.4L/100kms around town and the freeway from Geelong to Melbourne. First time i have figured that and am Very happy with those numbers

G'day mate - just came back from a trip (through Nanango also) in mine - tb42e also - and about to shock the pants off everyone with the figures ... mine are already off it's that exciting!!!! lololol ...

[Bigrig]

Righto here goes: 2536 kilometres - 90% highway driving but flooded roads, rain (had to run air con as bloody hot and peeing rain), usual amount of roadworks from the previous flood damage etc - two passengers, me and the missus with about 40-50 kilos of luggage etc - tyres at 39 psi. Took things fairly easy, but stayed on average around 105 on the highway - 5 to 10k's less as a cruising speed and I could probably rip another half or more litre per 100 off the numbers. Did probably 60-65% of the trip on LPG.

So after a long battle of trial and error, and with O2 sensor replaced and snorkel fitted the day before we left, these are the averages:

LPG - 20.92 litres per 100
Petrol - 17.94 litres per 100

Awesome is all I can say - still not the best figures in the world, but considering when I started looking into it I was getting around 24-26 litres/100 on the open highway (over 32-33 ltrs/100 around town), I am dead set stoked ... and I still have the extractors and 2.75" mandrel exhaust with high flow cat to go on yet - so these may improve even more ...

BigRig is a happy boy ...

[YNOT]

What size tyres are you running on? If you're on 33's like it says in your signature, having a second set of wheels with 31's on will bring your consumption down even further.

Tony

[Bigrig]

Tony - thanks mate, had a second set and sold them off ... not too interested in swapping them over as I normally don't do that much touring/distance as a stock standard road trip (i.e. would leave the bigger tyres on normally as I'd only be covering k's to get to a 4wd destination where I'd want the bigger tyres). Pretty bloody happy with the numbers, and as said, will hopefully come down a bit (or at least give more kick) with the extractors and exhaust - my brother bought a 94 TB42e last week with them on, and it would dead set leave me for dead off the mark (that much of a difference) ...

[Nanango]

Sorry to ruin your day Big Rig. Picked up my Patrol in Canberra today and headed on up to Sydney. 296.7KM later I had used 44.68L - That equates to 15.0589 L / 100 Km. You recon you are stoked. No A/C, but with roof rack and just nursing it along between 95 and 105 kph all the way in the 110Km limit. No traffic.

Top stuff mate - my brother's new rig just returned 12.5 ltres per 100 on highway driving also, so my world was shattered even before I heard your good news!! lol ...

[Nanango]

Tomorrow is a wander around Sydney then out to Richmond and up to the Central Coast. We will see what happens then. The next day, Central Coast to Coffs, but with the hammer lifted right off 85kph to 95kph to see what difference that makes. Then on Wednesday, a big one, Coffs to the Sunshine Coast then back trak and head out to home. Will keep the figures for each days run together with a total trip average. Still can't believe15L/100Km though. Maybee I did not fill it up properly when I hit Sydney, but the total trip average will tell all

[Bigrig]

Look forward to the results mate.

TB42e mate ... same as mine ... hence my depression at his consumption figures straight off the bat!! lololol ...

[Sir Roofy]

WELL fellas after reading three pages of threads our TB45E dual fuel auto is in the same ball park as most of them
our truck is stock standard running MAXXIS BIGHORNS 265/75 on38P.S.I thanks to BOB and his maths im getting 24lt/100ks
hwy and of course it would be higher in the bush
if i was to add a snorkel and bigger exaust pipe i wounder if this would improve the economy
i run mainly on gas as the petrol seems to dissapear very quickly

cheers roofy

[Bigrig]

Hey mate - not sure what did the most good as it were, but I had the O2 sensor replaced at the same time the snorkel went in, and as per my other post, I have dropped (easily) 4-5 litres per 100 on the highway ... I expect to get even more with the extractors and 2.75" exhaust .. that is a post Christmas add on though, so will be some time before I get to see the benefits ... as for the snorkel though, I reckon it's a given for any patrol (aside from all the other benefits).

[Nanango]

Yep confirm that. TB42E.
Just got back a couple of hours ago and for the complete trip - Canberra to Nanango with a few detours,, a total of 1700Km I averaged out 15.36L / 100Km

[Nanango]

I also have a complete breakdown of each leg, some flat out, some very careful driving, some with a/c on, some with hills and ranges. Will not post them tonight, but probably later on tomorrow night, as I have a pretty full day tomorrow and I am just about stuffed today after over 700 Km today, no a/c on,
i am just about all dried out with the heat.

Glad you made it safe and sound mate - look forward to the figures - will be interesting, as even the overall average is bloody good!!

[Nanango]

OK figures in detail. First, as mentioned TB42E , manual, roof rack, standard 15" tyres. did not use a/c unless mentioned. Drivers window down most of the way.
- Canberra to Sydney (297Km) sitting on the speed limit - 100 to 110 KPH not sure what fuel was in car when I picked it up = 15.06 L / 100Km
- Sydney to Richmond to Wyong to Newcastle (264Km) sitting on the speed limit standard 91 unleaded = 16.3 L / 100Km
- Newcastle to Coffs (388Km) sitting on between 80 to 90 Kph last fill up was with E10 91 unleaded = 13.87 L / 100Km
- Around Coffs (43Km) stop and go 50% with a/c on. Last fill up was standard 91 unleaded = 20.4 L / Km
- Coffs to Caboulture (456Km) sitting on the speed limit no a/c. Last fill up was standard 91 unleaded = 15.46L / 100Km
- Caboulture to Bli Bli to Woodford to Nanango stitting on speed limits. Hills, ranges, varied speed, Last fill up was E10 91 unleaded = 16.L / 100Km
- Total trip (1700Km) = 15.3644 L / 100Km

Conclusions
a) variation between 91 and E10 91 did not seem to make much difference
b) dropping highway speed from 100+ to approx 85 saved approx 1.3L /100Km
c) stop start driving with a/c on used approx 5L / 100Km more than highway miles

Thanks for the detailed information mate - greatly appreciate the effort and a good read. Top figures at the end of the day - driving style has so much to do with how much you use!!

[Sir Roofy]

hi boys
did a round trip of 329.9ks today in our 98 gu 4.5 auto on gas used 60lts gave me 18.19lt/100ks thats running mainly the freeway bit of heavy trafic and lights
thought that was ok
did some home town driving shopping ect and got 24ks/100
cheers roofy

[Nanango]

Assume you mean 24L / 100 for the home town driving. On gas those figures look good. Was tossing up to go dual fuel, but this one came up first and am still happy.

[Sir Roofy]

hi rick yes home town running ,would still go deiselif the opertunity comes up.better for touring ithink
roofy

[Sir Roofy]

hi bob
both our trucks must be well tuned as we can get them,might ghet a tad more with a snorkel
time will tell

[Bob]

A Diesel Patrol achieving 10l/100 k's would cost $12.50 assuming Diesel was $1.25 per Litre
A 4.5L Patrol achieving 20L/100K's would cost $11.80 assuming Gas was 59c per Litre
Not much difference. Havent done the exercise for Petrol but it would not compare with either Diesel or Gas.
Diesel would be the preference due to Power

[Bigrig]

Howdy - just finished the run to Sydney and back (and some surrounds), and pretty happy with the result ... essentially, since I've had Tank, I have replaced the air box, O2 sensor, coolant temp sensor, radiator, put in cold plugs, put in a colder thermostat, advanced the timing 4 degrees and had the valve clearances "set" a bit better for LPG ... that has seen me drop from around 22-23 litres per 100 on petrol, and 25 or thereabouts litres per 100 on LPG (both highway figures - not averages) to the following:

Petrol - 16.5l/100
LPG - 20.36l/100

Basically I have spent about $1400 to achieve (at petrol rates - lets say $1.35 per litre) a $8.77 per 100 running cost reduction ... means I'll see my return on investment around 16,000 klms from now *lmfao* ... but I am happy and that's all that counts .... apparently??

[Ben-e-boy]

I have a turboed td42 running 13psi and yesterday I filled up. I drove 1863km on 202L that is 10.8L/100kms and compared to others on here its pretty effing good.
It is all highway driving (long trips couple of hundred km + nothing less). my ute isnt a daily drive coz I have a company car. The last tank of fuel took 4 months to run down.

[tracemul7]

1997 GQ 2.8TD
Just filled her up today - got 585km on 68litres, so roughly 12L/100km.
Usually averaging highway 12-13L/100km, and local roads 15-16L/100Km.

And again, we're from UK too - so it's dirt cheap compared to the price of running my 1.4l petrol skoda :P

Question guys, how to save fuel for the GU 2006 Model ZD30 Any advice

[Dark 1]

Did around 4000klms over chrissie , mostly highway. Low load weight, roof rack with tent & space case. Averaged 14.83 ltrs /100klms.
Pretty happy with that.

[YNOT]

Question guys, how to save fuel for the GU 2006 Model ZD30 Any advice

Not much you can do.

Make the car as light as possile by removing unneccesary weight and remove roof rack if fitted. Fitting a more efficient exhaust system may help, and many people report getting better fuel economy after fitting one of the power chips to the engine computer.

Hi,

Patrol GR (Y61) 1998 RD28TDi

Driving between towns keeping up to 90-100 km/h – 10L/100
driving on a highway keeping up to 120-130 km/h – 13L/100
in city driving speeds up to 40-50 km/h – 15L/100
so when fuel prices in Bulgaria:
diesel - 1.27 euros per liter
petrol - 1.28 euros per liter
lpg - 0.61 euros per liter

[boggy2006]

turned out to be quote a popular thread this one!

I just got my best ever fuel consumption, 90% @ 100kph and 10% stop/start, managed 16.8l/100km on gas. Tyres at 40psi.

[Bob]

Just returned from a Trip to Porpunkah. Speedo reads 451 km's and Fuel Gauge is on Red Dot. (Gas)
300 km's towing a Jayco Dove Balance travelling up the Buckland Valley exploring Camping Spots.
The 300 k's was at 100/110 kph with the Air Conditioner on.
My Tank holds 106 Litres useable so that equates to 23.56 Litres per 100 k's. Not bad for 4500 GU

i have had absoluty no help from Nissan Australia they dont even return email, phone calls ,or bugger all ,worst mob i have ever delt with for after sales service,

the service boys where i bought the Nissan from are great but,............my fuel consumption is sh#t

keep us posted on how you go with Nissan please mate

[nowoolies]

well ive just run my Patrol on 2 x 100 klm runs and refuelled both times the farm and back.
and i got 5.45 klm per ltr the first fill,
and 5.48 klm per ltr the second fill
not happy with those figures

[damianovdd]

EUR1.37 is now the actual price of diesel...
is the prices of the fuel goes up in Au?

Damian
Yes, fuel is getting more expensive here in Aus. too.
Has been around $1.34 (with variations) but is pushing $1.40 now.
Don't know about Euros but our dollar is at the moment very close to the U.S.$
I'm from Adelaide in Sth. Aust. and we do have variations of up to 5c./l. between various suppliers
Nice hearing from the wrong side of the world!
Good luck

I suspect there is something wrong.

No Chris, I was just looking at these figures too - everyone seems to be talking approximate fuel usage of Around town - 30 ltr's/100 klms. (That is the people with similar vehicles).
We have a 1996 GQ Wagon RB30 3.0L Petrol. My hubbie was trying to get an idea of k's to a tank this week. We usually fill up the tank before running it too low so didn't know what the maximum k's we could get out of tank were - but we've nearly got the gauge down to the bottom now and have only done 305km on 95 litre tank unleaded. Think it's only got another 10 or so k's left in it, but that seems about right if you look at everyone elses figures ie 90ltrs/300km. I think they're just hungry - have told him it doesn't help that he puts his foot down occasionally either - think he just likes the sound of it lol.

Think it's only got another 10 or so k's left in it, but that seems about right if you look at everyone elses figures ie 90ltrs/300km. I think they're just hungry - have told him it doesn't help that he puts his foot down occasionally either - think he just likes the sound of it lol.

To work out Litres used per 100 k's Fill up Vehicle and record the K's shown on Speedo. After driving for say 150k's fill up again recording the Litres used and the Kilometres travelled since last fill and enter in the Calulator here http://motormouth.com.au/myvehicle/consumptioncalculator.aspx

TD42 with a blower at 11psi on 33" tyres, recovery gear second tank front and rear bars steps etc, in other words heavy around town 13.5L per 100klms. Best i have ever recorded is 12.6 around town. Going away in a few weekends will do a highway run see what it gets. Never really tried to get good economy out of it just drive it.

[thin on top]

Wow, this wont look good, but my 2.8 TDi is getting 10L per 100km on the highway since blocking the erg and adding the 2T to the oil

I thought as much. Not gonna try it on petrol though.. With only 30 litres I wouldnt get very far.

I thought the Aux Tank was 35 Litres Capacity but I am not really sure as I am not game to run to empty due to requiring Petrol to start. I could be wrong.
I have not tested Petrol Consumption but I might this weekend as I am going away on a trip.

I don't use 2T on my CRD but if I "hypothetically" had the ERG blocked (as the the vehicle is under warranty stating that blocking EGR is a no-no) I would see a very pleasant improvement in my around town economy of 1.5 LPH down to around 10.5 ish from 12.0 ish.

I am off on a camping trip weekend after next of 700 K's or so and looking very much forward to seeing the "hypothetical" results an EGR block would have when towing the Camper on EGR and LPH

You could be right Bob, it's bugger all, anyway. I only get about 50km's out of it if I'm real gentle. ( which I'm not) I stop/start on fuel, just because I've always been taught to run gas cars on fuel time to time. Not sure if you need to.

[nowoolies]

well ive had the first of the excuses from Nissan on my fuel (and it took a call from me i might add just over a month for a reply)
they now claim its not to bad
and that their tests are done for the govt ..........and get a load of this ....in a wind tunnel and thats how they come up with 10.7 klm / ltr
what a load of horsesh#t
i voiced my displeasure and am supposed to be getting a reply back

My Truck when switched to Gas always starts on Petrol and switches itself to Gas after warm up. Yours should do the same.

[boggy2006]

mine's manual switch over, need to start on petrol, but can immediately switch to gas, even when cold. It will start on gas if within about 30 mins of stopping a hot engine, but any longer I have to use petrol to start it.

[gec]

Mine is a GQ with 4" lift, winch and winch bar,drawers fully loaded, fridge, 33s and my fat arse and still gets 16 to 17ltr/ 100 out of an LS1 5.7 so very happy lol

[Bob]

Just tested the 4500 GU on Petrol and around town achieved 17.96 Litres per 100 K's.
Run it on Gas most of the time which is a damn lot cheaper than Petrol

Ran mine with the consult unit the other day to go pick up the kids - 19klm round trip and not overly stop/start as we are a bit out of the city, and I averaged 23.7 lph for the trip ... my heart nearly stopped!!! LOL

Depends when the LPG system was fitted Kat - mine doesn't even do the "pre-squirt" of petrol when starting on gas, so I have to start on petrol when cold, wait till it starts to warm and then switch to LPG - it was installed in 2007. Mine isn't gas injectors either.

So presquirt was post 07 ? I think mine was fitted 2000ish. I just start it on petrol out of habit. Will have all that looked into when I get tank done.

Not sure when they came in, but probably before or around that time - May 2007 mine went in (through previous owner) and it is a bit of a dinosaur now ...

[the evil twin]

Mine was 2001... On "LPG" it started and ran on gas, on "Petty" it started and ran on Petty. With LPG selected it even disabled the Fuel Pump as I split an injector feed line crush seal one day and Petrol spewed everywhere (scared crappola out of me, how it never flashed over I'll never know) left it on LPG and I drove it that way for a while till I got a chance to fix it.

With roof bars and 2"lift and standard tyres:
1) 17L/100km combined (70%city 30% highway) on 98 unleaded
2) 22.5L/100km combined (as per above) on gas

Now with 33" MT ATZ 4Rib
1) 18.5L/100km combined on 98
2) 24L/100km on gas

Hope this helps.
I have a 90L gas tank and a 60L petrol tank.
So I guess that equates to 375km's on gas and 325km's on 98RON.

With Larger Tyres your Consumption would be different due to the difference in ground covered by one revolution of your larger wheel and the fact that your Speedo would not take this into account.

It would be an interesting exercise to find out if Lifts affect Fuel usuage.

Some items that affect Fuel usuage :-

Roof Racks
Tyre Pressure
Loads
Towing Caravans etc

I am not qualified to make any judgements on Fuel Usuage but it is an interesting subject.

Lift sure does... at higher speeds anyway. Would be too small to notice below maybe 50 or 60 KPH outside of a lab. Up around 100 KPH would be different as drag is exponential not linear.

The lift increases the drag of the vehicle due to an apparent increase in frontal size. A percentage of the air that "used to" flow over the top now has to find a different path and the alternative paths have higher drag characteristics due to compressibility and turbulence.

Just another of those little things that are relatively insignificant in themselves but cumulative effect is noticeable in the sky rocket

Agreed - lifting the vehicle generally gives more forward facing surface area of underbody components and would increase the drag effect on wind traveling beneath the vehicle - that said, having a GQ is like putting a besser block on wheels aerodynamically speaking, so as per ET's comments, outside of strict testing environments, it would be extremely difficult to measure actual increases in consumption.

Those figures seem a bit high

My Usuage is 18.5 Litres per 100 on Gas on a trip and around town 22 Litres per 100 k's same on Petrol
Roofy and Katrol are about the same.

With your 33" Tyres is your Speedo correct because putting on larger tyres you are actually covering more distance than your Speedo is saying and will affect Fuel Usuage

How long has your Patrol had a tune. Mine is tuned more for Gas Use and therefore one of the reasons better Gas consumption than yours

[TuffTD42]

91 GQ TD42, GT2871 turbo running 18psi, 3" exh, pump timing advanced & fuel turned up 6" lift running 35's. Around town driving all different ways i.e normal mixed with giving it a hard time 14ltr/100klm or 20.18mpg. I'm off to QLD to visit relo's over Easter so I'll get back with some figures for the trip as it'll be it's first trip since turbo & 35's being fitted.

Thanks Bob - I've just had it serviced and a bit of a tune up, so will keep an eye on the consumption over the next few weeks! Cheers.

[Bigrig]

Figures from yesterday - 15.3 lph on petrol and 18.9 lph on gas!! Stoked with those numbers!! This is the same vehicle that was struggling to crack 23-24 lph on petrol when I got it and 25-26 lph on gas!! Persistence and proper tuning through someone who knows what they are doing (Derek, not me!! LOL!!) is worth every penny. Average price for 95 unleaded is now around $1.40 up here, so that equates to at least $11.20 per hundred klms cheaper on petrol - considering I do about half half between the two and do about 25000 klms per year, that's a saving of at least $1400 per year just on petrol!!!

Hello, My Patorl 2,8 TDI `94 is consume 13 l/100km.

Hiya, around town my TB45S with manual tranny gives between 25-27l/100km. Out of town things improve somewhat with figures of 18-20l/100km! Tyres currently 235/85R16s, equivalent roughly to 32".

[TuffTD42]

Done my trip & got 13l/100klm on the way up not sparing the horses either. Towed a 7x4 off road box trailer back that I'd bought whilst up there & got 14l/100klm on the return trip also not sparing the horses. Might have to drive miss daisy on the next trip & see what the figures are then.

I'm starting to realise that mate .. mine was the same though, and it did take some coin to get it better, but certainly less than what I'll save on consumption now. I think my original post last year I was sitting around 25lph for gas, and now down to about 16-17 unladen ... and that should be even lower according to the guy I use if I got gas injection (I have the older system also).

I might ask him what he's actually done to get it down - I know thing s like the timing being advanced to 14 (4 degrees) etc, but he's obviously worked a bit of magic!! I'll post up what I find out ....

I will run a whole tank through next time and record the numbers I get as I have never had fuel consumption figures so low. This is new territory for me. I am used to having crappy fuel efficiency. I got 17L/100kms out of petrol last time i filled up. When I get my new O2 sensor I should get some better more accurate figures also.

The choke seems to stay on for a long time will try and work that one out on the weekend. I will be fitting a snorkel soon and from what I read on here maybe change the o2 sensor (how much are they and where do I get them?).
I am pretty happy at this stage the old Conformadore was giving me about 18ltrs per 100 on gas and I know what i would rather be driving.

Ok Guys, thought i would post up my latest Fuel consumption figures..
I cruise around in my troll, and don't 'Drive it like i stole it'

My troll is a 2002 3ltr Manual with:
- 3" Lift
- 33" Muddies
- Roofrack with awning, shovel, axe and 4 D'Lights all bolted on
- Steel bar, and D'Lights

My Troll does not have any performance mods (eg: Chip or exhaust).. It does have EGR blocked and NADS fitted
Boost is set to Max of 16psi, at 100kms'h boost sits about 12psi (exhaust temps about 300 Degrees)

Around Town at the moment i average around 14.6ltr's per 100
On the Highway as it stands i average around 13.1 ltr's per 100

Personally i reckon thats pretty good!!

1992 GQ ST WAGON RB30
just did a trip on the weekend with the club, i did approx 300km and wait for it,..............................................u sed 90ltrs of unleaded
I suspect there is something wrong.

Dude. Thats normal with the RB30. My first troll was a 91 GQ with RB30. Best i ever got was 450 kms out of 90 liters. Get dual fuel going man.
Now im getting 900kms out of 125 litres in my ZD30 GU.
Still trying to get below 14lt per 100kms, though.

[adrian]

I reckon I get about 650Km from a tank in the TD42, so whats that, 65Km per 10L . . .ish

[frenzy]

My 3 litre TD powered 2006 GU with auto gearbox, bullbar, roofracks, 2 inch lift, 33 inch muddies, 3 inch exhaust and a bit of junk in the back gets between 13.2 and 15.8 litres/100kms.

Sometimes, I idle all the way to work.... Haven't really looked into the difference between idling 15kays and doing 60-80km/hr.

finally worked out consumption for my 4.5 on gas running 35s with bout 50/50 mix of high way and city driving was 24.4 ltrs pre 100 dont even wont to know what it would be on petrol

[weetibix]

I'm afraid I have to ask a question here in real girlie terms here ;-)

I drive a Nissan Patrol '89, it runs on LPG and petrol.
If I drive it on petrol I only get about 200km out of one tank, sometimes even less. Also, the tank never seems to fill up all the way or at least the indicator never shows it does. Seems to only be 80% full.
LPG seems to last a bit longer but I don't think I could get more that 450km out of both tanks...this is normal everyday driving on sealed roads, no 4wd, no towing, no big loads.
Could someone please tell me if this is normal? I have to admit I have no idea....but I love my car :-)

Thanks guys!

[omgmud]

iam getting around 14-15 ltrs i think. did 770kms and filled up with 110ltrs of diesel. that was going from parramatta driving around woolongong through all the hills in kangaroo valley, up through bowral to campbelltown and back home. and also general driving to work and back etc. does this sound good?
its a 89 n/a deisel. with 415000kms on it. has 33s 6"lift bullbar winch custom rearbar. and apparently fuel pump has been turned up by previous owner. wether thats true or not unsure

[Glen 93 patrol]

my new truck is a 93 ti with the tb42, has 35's on it and no gas. last few tanks around town were between 15-16L/100km. on the highway it used 12L/100km. not too bad as previous owner said it sucks 20L no matter what the conditions are.

[megatexture]

maybe he ment how much he drinks per day:1062:

[gec]

I'm starting to realise that mate .. mine was the same though, and it did take some coin to get it better, but certainly less than what I'll save on consumption now. I think my original post last year I was sitting around 25lph for gas, and now down to about 16-17 unladen ... and that should be even lower according to the guy I use if I got gas injection (I have the older system also).

I might ask him what he's actually done to get it down - I know thing s like the timing being advanced to 14 (4 degrees) etc, but he's obviously worked a bit of magic!! I'll post up what I find out ....

So Bigrig, When are you gonna post up what you had done, as my young bloke has a GQ with the TB42E on dual fuel and his consumption is horrendous, he is saving for some mods to make things better like headers, exhaust, new airbox, and computer, but if you have any other suggestions as to what he can do it would be much appreciated, Cheers.

2000 GU 4.5 litre Automatic 265/70/16 AT's, no accessories, just a big fat man in the drivers seat and running 98, around town 12.9 litres per hundred. That is the best that i have gotten. Mind you that is pretty much how i drive all the time. Couldn't tell you what it is on the highway.

[malcolm]

Hi , 1991 maverick lwb , td42 , 330,0000 kms .standard spec. just come back from a short trip from Sydney to Hill End about 640kms round trip - loaded with camping gear 2 people , push bikes on roof etc - averaged 12.5 litres /100kms - Not bad for crossing blue mountains there and back.
over fueling slightly - blowing some black smoke on up hill sections - so may be able to improve slightly ?
Cheers .

[Drew]

11.6L/100Km was 12.4 last tank. 30% city/70% hwy

[Kurt W]

03 ST with ZD30 Di - 142k 0n the clock, 32.5" Coopers, every thing else is standard - no roofrack and no load.
Ok, so I filled main tank today, needle was just above quater - took 71.8l after 722km. So that makes it 9.9l/100!!
300km was around town, 200km highway and 200km hill country of Mt Mee and Blackall Range.
This was done just after an oil change and all the filters and the Maf sensor clean.

I'm happy with that!!! A good benchmark to see what happens as things get added!!

iam getting around 14-15 ltrs i think. did 770kms and filled up with 110ltrs of diesel. that was going from parramatta driving around woolongong through all the hills in kangaroo valley, up through bowral to campbelltown and back home. and also general driving to work and back etc. does this sound good?
its a 89 n/a deisel. with 415000kms on it. has 33s 6"lift bullbar winch custom rearbar. and apparently fuel pump has been turned up by previous owner. wether thats true or not unsure

I got an 88 NA diesel with 33" muds and 4" lift, front steel winch bar and 410 000ks so we are pretty similar. I drove from brisbane to cairns and while i can't remember exactly the figures out of the 120 litre tank i can get 800k's with a bit left over. It equaled 12litres per 100 and seems pretty consistent at that figure. I think the pump is stock. I am about to fit a turbo so it will be interesting to see if the engine handles it and what the fuel consumption does.

Will need to do a few more tanks yet to confirm but it looks like I have dropped in usage a bit since the new pipes have been put on, somewhere around 19-20L/100 I am guessing

02 3ltr Turbo, auto wagon.In April, I bought this wagon, and done a few 'approved mods'. The best money spent was a dyno-tune (Websters @ Wodonga), and clean-up of intercooler (flushed).
Car runs much better, more power & improved fuel economy.
Went over Thredbo & back last week. Am pulling almost 700 klms out of the main tank! Some quick calcs, it's doing just over 11 ltrs/100 klm. Very happy :)

Hi Forum members we need to help Weetbix with his truck, his fuel figures are woeful. I've asked him to post a new thread so we can all help. 200k per tank is just not on.

[danielrusty]

I just drove from Sydney - Adelaide - Perth in my 4.8ltr petrol, "06" Its had a cruise control accessory put in which was extremely comfortable however i found it ate more fuel whilst on cruise control. I was chugging through a 90 ltr tank every 400-500kms. I haven't done the sums yet but i will post them soon. Can anyone tell me at what point does the red light indicator come on the fuel guage? When there's 50ltrs or 50 kms left, something like this?? Its the Y61 wagon.

[Wine_maker]

Before engine (RD 28T) rebuild:

City - 16-18 litters
Highway (80-95 km/h) - 14-16
Highway (100-120 km/h) - 20-25

Most economy regime in my shorty in range 1900-2000 rpm. (before turbo work 2200 rpm)

Vehicle without any modifications.

I get around 14l/100km in my guiv 4.2td with 33" 2", llift, steel rear bar, steel front bar and winch and about 100kg in back of the wagon. Had mild tune and running 3" exhaust. My bother with the same vehicle, weight, tyres and lift gets 15.5l/100km.

[alexx]

my zd30 '04 got 7 kms/l under heavy traffic and 10-11 kms/l in highway

[Steveo_the_Devo]

2011 3.0 CRD, 20k on clock. Steel bar & winch, rear drawers, fridge, 2" lift, std tyres.

Fully loaded with kids, camping/recovery gear, food & towing camper trailer = 15.5l/100km with cruise control at 95km/hr. Up to 19l/100 if punching it up to 120km/hr (NT roads of course).

Around town & unloaded (still has drawers & fridge in) - 13.5l/100.

Hoping for better figures than that with a few more km & some exhaust mods.

[The BigFella]

Our 45 petrol/lpg runs around town for .18c per k and .16c per k highway driving.
These costs are for LPG not petrol.

[DX grunt]

2005, 4.2 TDi, 229k's on the clock Ex Telstra ute with a pod on the back.

Fuel consumption increases when I drive it like I stole it. PML. I'm just starting to monitor fuel consumption and so far, it's just been just under 15l per 100ks.

This varies if the road is wet and if I'm driving on gravel roads (mostly drive in H4), and how much crap I carry in the pod. I've got 'cheesecutters', to motor me along.

Truck weight includes: me, a Steel bull bar, winch, spotties, HF auto tune aerial, 2 x spare tyres, full recovery gear, 95lt Evakool fridge/freezer, 20lts of fresh water and tools.

Pod sticks out about 6" alll round and acts like an anchor in a head wind and the truck handles like a wobby tissue box in a cross wind. lol

I love my truck.

Take care out there.

Averaging 24.17L/100km, had it as low as 22.14 and as high as 30.88. It has gone down a little since switching to smaller tyres. I reckon I could get it down to 20 if I did only highway driving, I'm going up to Lakes Entrance soon so I will try that out.

Probably being a little higher might effect the patrols silky smooth aero dynamics and catch a little more wind. Lmao

tyre pressures effect the rolling resistance a fair bit.

[Dingo55]

Some simple, easy to follow instructions on how to improve fuel consumption, mmmmm ?????

http://www.ehow.com/how_7469758_improve-gas-mileage-jacked_up-trucks.html
Instructions
1 Limit the amount of aftermarket accessorizing for your lifted pickup and/or try to be selective in the type of accessories you add. One of the benefits of jacking up a truck is the ability to fit larger tires and wheels. If possible, though, choose alloy or aluminum wheels rather than steel, as steel wheels will add unnecessary weight. Also avoid adding numerous exterior accessories, such as light bars, roll bars, step bars, winches, hitches or grille guards. Extremely large tires with off-road tread will also diminish fuel economy.

2 Drive your jacked-up truck at slower speeds when traveling on the highway. Because the truck sits higher off the ground, it encounters more air resistance and drag. This lack of aerodynamics hinders the truck's gas mileage at high speeds. Thus, driving the jacked-up truck at 55 mph or lower will help improve its efficiency.

3 Avoid using the truck's four-wheel drive whenever possible. Most lifted trucks are four-wheel-drive capable, whether it's at the push of a button or whether you have to lock in the manual hubs. Using four-wheel drive, however, comes at the cost of increased gas usage. Thus, switch over to using two-wheel drive any time you encounter good driving conditions. Four-wheel drive should only be utilized when it's absolutely necessary.

4 Avoid using your lifted pickup truck for daily errands or multiple, small trips. If you can, opt for a different, more economical household vehicle instead. This way, you'll save both money and gas. Use your jacked-up truck only when necessary or for recreational off-roading.

5 Check the tires and their alignment. First, make sure the tires are fully inflated. If they're underinflated, your truck will experience a loss in fuel economy. Also, if you've installed larger all-terrain or mud tires, you must make sure they're properly aligned by a professional. If the tires are out of line, you'll also experience diminished fuel mileage.

[Boagie]

So my big girl has gone from just under 10 ltrs per 100k to about 11.5 ltrs per 100k.This only happened when i have put extractors and fitted a k&n air filter??has anyone else had similar dramas after makin their patrol breath a little better?????

[Winnie]

Nope, in fact putting extractors on mine decreased fuel economy quite a bit, about 3L/100km, so it was a big difference.
I have a different engine though.

[Tank]

1991 td42 (non turboed) LWB 33" muds
Boy I think I have a problem, filled the tank , zeroed the trip meter drove around till we got to half a tank and then filled it up again. 43lt and only 2.3km!!!!! By my math that works out at 1886ltrs per 100km
Then figured it wasnt worth fixing the odo and trip meterso I did the same excerise with the gps and got 12.6 lt per 100km and felt better about life

[GQ TANK]

Im getting the same fuel econ has I had with the L28 running rb30s

rb30 & l28

15k/l petrol
22 L/ l00 lpg

TB4.2 carby - getting 23 l/100

[Winnie]

I filled up in Traralgon, drove around the town there for a while, went up to Lakes and from there drove to Warragul. 382.7km and used 78.86L of LPG, that's 20.61L/100km
Not bad, I was happy with that and I was sitting on 110km the whole way back from Lakes so it could have been a fair bit better.

Remember you will always see a decrease in economy fitting larger tyres. Your car is calibrated for 265's so throwing a 305 on it means that the wheel tyre combo is doing less revolutions to cover the same distance. This will read less on your trip/odo meter as its all calculated for the smaller diameter factory fitted rubber.

For example a mate and I did a 150km trip, he was on 35's, I was on 33's, we pulled up at a servo nearing our destination and my trip meter said I had travelled 20km extra then he did. (both trip meters set to 0 at start of trip). We had identical running gear, engines, gearboxes and diff ratios.

30.76 litres per hundred k's!!!!!

Holy footy socks down the jocks batman!!!! lmao

But alas, the price I've paid and willing to continue paying currently for having a shed load of power at my beck and call ...

Normally average about 17-18 lph on the highway unladen so these figures above aren't the norm by any stretch.

[rowlund]

I have had my 2002 4.5 liter petrol GU for a couple of weeks now. I have gotten the hang of feathering the throttle, using the vehicle's own momentum, gliding to a stoplight, all to maximize the fuel consumption of my GU. At the onset I was very conscious of the fuel consumption figures of my patrol. After a week of using it though, I have come to accept that my GU is like a person with a diabetes in that the thing is always thirsty. Given the comfort, durability of the GU, I can say it's well worth it.

[Jock]

My 2010 auto with BB, snorkel and DB with accurate records kept over the last 14 months I am getting 14.8L/100km. These figures are made up 50% towing 1600kg, 25% 4x4 and 25 general town driving. I tow at 90-100km/H. I'm pretty happy with these figures.

Distance covered = 6211.6 km's
Diesel used = 868.44 ltrs
Average Ltr/100k = 13.98
Great trip speeds varied as you know If you've done this trip, this included going accross to Weipa then up the ol' Tele track
Started Sept 12 arrived back in Lismore 1st Oct, short timeframe as had to get back repack & take the handbrake to Bathurst for the V8's.
highest fuel uasage was on way home from Gympie to Lismore where I was sitting most of time on bout 110k/hr & used 16.13ltr/100k
Can't wait to do this trip again but with a lot more time up my sleeve.

Ooops forgot to add she's got 332,000 n a bit km's on the clock & running 32's n lift

Just did a metering on my economy in my patrol 98' 2.8 GU with 303000km on the clock bog standard,

Travelled 880km with approx. 300km being a return trip to Port Macquarie and back, and the rest around town, Used 107.34L which works out to be about 12.2L/100km


Have thought about the egr blocking plate etc, but would like to at least know what boost I am currently running so might get that monitored first.

[oigioioi]

I have a 2002 Gu III patrol, 3.0 Turbo Diesel, Manual. Also running Manual boost, blocked EGR ect....
I average around 10 litres to 100km's on a highway, thats sitting on 100km/h.. Sits around 10-12psi boost and 260-300 on the pyro
Around town i get around 12 or so litres to 100km's. Boost and temps vary depending on how heavy my right foot is that day haha

Thats not to bad i dont reckon

Hi, look like you had done the job I would like to do. I have o7 Turbo diesel.ZD30 and I would like to block EGR and do manual boost, fit gauges etc. But I am absolutely do not have any experience on it. May I ask you to give me give me advice for this job?
If you can, I will give you my email address and we can contact by email.

Christmas drive from Stanthorpe down to brissy/Beenleigh via beaudesert and back through Mt lindsay rd via Legume to Home, clocked just on 1200 k's for a usage of around 160 litres and if i remember right (i am drunk) 13.46 l/100k's. All in a 2006 gu ute, with after market turbo and 3" mandrel exhaust

[lorrieandjas]

Just did Sydney to Brisbane and for red light on and a little in the sub left did just over 1100km so about 11.2L/100km. Not towing but was loaded with about 100kgs, steel bar and winch. Only 3000 on the clock so happy with that. Speeds varied from 80 to 110. On the way down averaged about 13L/100km. Dunno why.

Anyone know when/how much boost the turbo adds and what the power curve looks like on the GU IV series?

Just owned my Patrol for a few days now, and trying to work out what the best rev range is for fuel economy/power...

Thanks

[boots]

04 GU STL auto ZD30 now with beaudesert 2 3/4 '' exhaust . Last three tanks 73L / 700KM , 80L / 778KM , 107L / 974KM . mixed driving conditions ie - highway / running around . Very pleased with the exhaust and the improvement it has made to the 4B .

[Cuppa]

2006 TDi4.2 cab chassis with telstra pod (wider than cab) with rooftop tent & solar panel on cab roof (ie. a fair bit of extra wind resistance), plus a lot of weight (unsure how much, but camper includes 180 litres of water (180kg), 3 x 120 ah batteries,(105kg) 420w of solar panel.(?45kg) Rooftop tent (70kg) Oztent(?35kg - maybe more). 60 litre & 40 litre fridges on slides (?kg). food, tools, recovery gear, etc etc. Plus steel bullbar, winch, dual spares etc. So fairly heavy.

Driving for economy - averaging 90kh to 100kph - on mostly open road, but including perhaps 200kms of 40 to 60kph dirt road, & 60kms of slower 'mild' 4wd'ing.

On two full tanks (main & sub - assuming 95litres & 70 litres capacity - didn't check) I went onto empty just at 1070 kilometres.

this works out at around 6.5kms per litre or 15.5 litres per 100kms.

I expect that I could have got a few more kms before actually running dry, & also that it is likely that it is not possible to use every drop of fuel in the tanks. On this basis I feel comfortable in claiming 15 litres per 100kms or better. Not as good as some, but considering the vehicle's configuration reasonably acceptable I think.
What is pleasing is the range of 1000kms+ with a pretty reasonable safety margin.

Cooling system hasn't even got a thermostat so will be flushing the system and putting one in and hopefully will improve this figure.

[healy]

Has anyone done the Rb 30 efi and turbo conversion? What sort of output and fuel economy figures did you get?

With a stock standard carby and tyres . 80% Highway and 20% stop start, I got 14.83lt / 100 ks
That's not bad mate for an rb I was getting 20+ with 35s on my carb and and ship load of after market gear in it

Have you changed the diff ratios, because 20 plus ltrs / 100ks is about what I normally seem to use when towing or off road work. Since my first post, I found that the Dissy cap was stuffed. After it was replaced and the spark plug gap adjusted, I noticed a very slight increase in power so I will try to see if economy has improved.

[Wazza_66]

I was getting around the 10.4/100km and since fitting the winch I am getting around 11/100km. will be interesting when I have to put new tyres on it and go up from standard to 33's.

[threedogs]

Somethings going on and I can't put my finger on it. my 04 is running great all nadded out etc.
since fitting the 305's Tyres by half tank I'm normally around 300-310 k. This tank load I managed 360 kilometres.
Never,ever,ever produced those figures. Even with my 285s I only get 320-330 tops to half tank. Going by these
figures I'd get 400 k with my ATRs. Weird I reckon.

[NP99]

I'm getting about 20/100k on a 99 4.5 duel fuel.

[Coldcomfort]

I just did the numbers on my GU8 3liter manual. Driving around town (the Alice) air con 100% of the time. I am getting 11.53 L / 100. The car has done 6000klms now. My last figures gave me 12.3 L / 100. It seems to have improved with a bit of driving.

[threedogs]

Used 3/4 of the main tank towing my camper to the murray and back total of 500k
sat on 110kph with 305 muddies

[Michaelh]

Hi. Just come back from a Queensland trip via Sydney both up and back. A mix of highway cursing at 110km to stuck in traffic. 4483.8 Kilometres used 682.97 litres, mileage was 15.23 l/100k. Vehicle is a GU7 3.0CRD. full loaded with 2 adults, 3 kids, roof rack and luggage.

[Gerry]

Good point thanks mate!

[rusty_nail]

im currently sitting on close to 30ltrs to the 100k on gas. im at a loss of how to fix it also!

[paps01]

I have a GU DX TD42TI ute with a camper on the back which weighs close to 3,900 kgs. The thing that amazes me is not so much the consumption but how regular it is. 12,000 K's to cape york and back 16.7 ltrs. Recent 1700 k trip around vic and nsw, 16.54 ltr's. both trips all conditions except extended sand.

[paps01]

You'll find your tanks are 90 and 85, 175 all up.

2006 TDi4.2 cab chassis with telstra pod (wider than cab) with rooftop tent & solar panel on cab roof (ie. a fair bit of extra wind resistance), plus a lot of weight (unsure how much, but camper includes 180 litres of water (180kg), 3 x 120 ah batteries,(105kg) 420w of solar panel.(?45kg) Rooftop tent (70kg) Oztent(?35kg - maybe more). 60 litre & 40 litre fridges on slides (?kg). food, tools, recovery gear, etc etc. Plus steel bullbar, winch, dual spares etc. So fairly heavy.

Driving for economy - averaging 90kh to 100kph - on mostly open road, but including perhaps 200kms of 40 to 60kph dirt road, & 60kms of slower 'mild' 4wd'ing.

On two full tanks (main & sub - assuming 95litres & 70 litres capacity - didn't check) I went onto empty just at 1070 kilometres.

this works out at around 6.5kms per litre or 15.5 litres per 100kms.

I expect that I could have got a few more kms before actually running dry, & also that it is likely that it is not possible to use every drop of fuel in the tanks. On this basis I feel comfortable in claiming 15 litres per 100kms or better. Not as good as some, but considering the vehicle's configuration reasonably acceptable I think.
What is pleasing is the range of 1000kms+ with a pretty reasonable safety margin.

My 4.5 returns 18L/100K's Cruising so you should get approx the same with your 4.2.
My Car is tuned by a LPG Specialist as most normal Mechanics have a little trouble tuning for Gas

yeah i just took it to an LPG specialist who tuned it up. he made it run smoother with better performance but couldnt improve the fuel economy...

[Lonicus]

Just did a quick run, Bathurst to Maitland and back, around 700klm. Bathurst to Maitland averaged 9.3l/100, return trip was 11.2l/100. 2 people and little luggage on board. Pretty much just kept to speed limits up and down hills. Pretty pleased with the results.

[Sir Roofy]

Fueled up at narnargoon friday arvo topped up the tank with 42 lt of fuel went to tallarook
drove a couple of tracks and drove home sunday total klm 398.7=10.68 l per100 im happy with that
gu 3l turbo wagon

[Winnie]

Roofy you need to fill up again to be able to work out consumption for the trip.
I filled up on the way there and filled up on the way home. Used 20L/100km which I don't really think is that bad as most was low range and we were driving for a long time.


If you're happy and you know it tap a post!

to doit that way i should have filled up at the goon but im sure its no different

[Winnie]

Yes but that doesn't mean you used 42L on our trip. Where was the 400km from? I filled up in the Goon on the way in and on the way out and was about 300kms with some extra tracks this morning

2012 ST. Just did the numbers again. 9.8 liters per 100klms. Air con only on about half the time now... 9500 ish klms on the odo. Very happy with this.

[boots]

93 litres / 825 km .= 8.87 km / litre , 11.27 litre per 100 km . Just fueled after last long weekend trip away to east gippsland and running around town the rest . 04 GU ZD30 auto with mods . Still very happy with my 4B and its performance .

[MEGOMONSTER]

Over the long weekend to Bearii with a full boat and car of camping gear plus a week of driving to work. DPCHIP on 7 for the trip
164.93 litres to 1243kms = 13.27 L/100k

[Wizard52]

Just returned from 3 weeks on Fraser. Did 645klm and used 133 lt - 20.6 lt per 100klm or 4.8 klm per lt.
All but 40 klm on sand and most of it loose and dry and chopped up quite badly. Drive down from Indian Head to Eurong was good hard sand at low tide but rest including trips across island was slow 1st and 2nd high range work. Normal on road consumption is about 13 lt per 100klm

[smicko]

07 4.8 with extractors and 3" exhaust, full cage roof rack on 33"s always run on 98ron and pretty well always returns 19-20l/100. Seems to be something wrong with the loud pedal as it doesn't want to go slow.
Did a recent run to Exmouth with a heavily laden tinny and boards on the roof and best was 16.6/100 (about 100km/h) and worst was 21.6/100 (about 130km/h with both air cons flat chat)

[Newman4087]

1990 3L rb30 - I get 150-180kms out of a full tank (85L).. Surely this isn't normal fuel consumption?

Between 47-56 lt per 100klm, i highly doubt that is correct.

Hi chuck here.
The 2012 GUis good for its size!
On the trip to Mildura via Benlow State park we managed 12 lt / 100k with a 700kg camper,

Hi All
Just did a run up to Cervantes and back for Easter (around 660kms all up). Most of the trip dome at 110km/h, some time spent 4WDing in soft sand and touring around the town. Returned 12l/100km. Not too bad as I was pushing a bit up the hills. I suspect it would be a bit more economical to sit on 100km/h tho.

ZD30 auto. 305/70/16.

[markusa]

Hi all,

my '92 GU uses around 11l of diesel per 100km during trips. It is over 350k km already. Often towing the rally car. And then consumption is... hmmm ... higer ;)

[BigRAWesty]

11/100 mate that's awesome

[Dr Gary]

I have a GU 2006 3.0 with exhaust and snorkel, otherwise all standard. Just completed very heavily loaded (all camping gear etc) trip from Gold Coast to Alice Springs via Plenty highway, then south to Marla, Oodnadatta, (road all mud and water-heavy going) then back home via Birdsville. Total 7,287 km and 920 litres for 12.3/100. Best was a slow cruise at 80 km/hr for 10 l/100.
Town mileage is usually 13 +

[Darryl Weber]

Hi Dr Gary,doing a similar trip with a 3.0 myself in 6 weeks time. From Toowoomba to Alice Springs then on to Katherine Gorge back over to Townsville and back down the coast towing a 14' van. I hope to get 10 -11 litres/100. I have chip,3"exhaust and snorkel fitted to mine. Fuel economy is awesome since fitting these mods!!! Can't wait to get going and having a look at our backyard. Cheers Fang.

[Dr Gary]

We went via Boulia and Plenty Highway. The Plenty is VERY rough and we decided next time to go further north via Barkley Tablelands. That would be a reasonable choice returning to Townsville.
If you choose the Plenty, allow extra time and keep fuel topped up--we got caught at Gem Tree where fuel was $2.30, while Alice was only 140 k down the road and much cheaper.
Let me know how your economy works out

[TimE]

Over the past 14,000 ks in my 4.2 tdi GU IV running 33s I have averaged 15.56 l/100km. Worst 19.95 (Simpson Desert) best 12.56 (Stuart Highway with tail wind).

I use an free app, Total Fuel, to keep track of my fuel consumption.

[grahamap]

As it stands on this current tank of fuel. . 35 litres got me 175km 90-100kmh highway.. I think something is wrong lol @4km/l with an l28

[Darryl Weber]

Six weeks ago bought my first Patrol a 2001 GUII ZD30 manual. Wanting to get an idea of the fuel economy I filled both tanks and drove from Toowoomba to Brissy(nth side of city)twice in one day some 600 kays.Done approx 300 kays of stop start town driving and then put 1100 kilo van behind it.Towed it on the highway about 80 kays and spent a couple of hours teaching wife how to reverse van and tow on the highway.Returned to servo with 1002 kays on trip counter and refilled it.To my surprise it only took 92 litres!! I used Caltex Vortec diesel so maybe there is something in that I don't know.Vehicle is fitted with a snorkel and a Stienbaur otherwise it is standard and running 265/70 16 maxis tyres. Am I happy with that,hell yeah I am. Had an old B series Mazda dualcab before that. It guzzled 65 litres every 450 kays on highway or 350 commuting in town!!! And that was driving it like I had a rusty nail under my right foot! Taking Patrol to Ayers Rock in 5 weeks time towing the van so will report fuel economy again when I get back.

[HuskyInAuz]

After installing the Brown Davis Aux LT tank took it for a drive. Vincentia, Canberra x2, up and down the hills and I wasn't kind about keeping the speed and RPM's up.
12.8 l / 100

[Badball]

Just done a trip to Vic from Adelaide, recently added the roof rack, Snorkel and 33in tyres. I just got 12.1L/100km and was very surprised. I worked out that the odometer is out 10% with the upgrade tyre size using my GPS. I have read that some people have an increase in fuel consumption am wondering if they don't account for the odometer Being out when working out their fuel consumption? In saying this, I didn't think it be down to 12.1l with the roof rack. Has anyone got an improvement adding the snorkel?

[HuskyInAuz]

just went from Mission Beach Qld (aka Tia VIC juana nord) to south of Bowen with a 20+kt headwind and three cargo boxes on the rack and CSU. 16.7/100
that's the worst on the trip so far

[bindi]

3.0 CRD MANUAL with full length roof rack and 2" lift

bodding around town, to and from work (12L/100)
Highway cruising (11L/100)
Towing a 17'6 caravan which has a tare of 2.1T, which is probably close to 2.5 loaded. (17L/100)

averages over last 6 months, and calculate litres to full and kms.

.....Just done 6000kms upto QLD and back and it varied between 16.8 and 17.8, apart from driving into a crazy strong headwind and it went upto 20L/100.

All in all, fairly happy. My BMW X5 averaged 8.5L/100 solo, and 14.5L/100 towing, but the paddy goes places the beemer would just would not :)

[91TB42]

I've just bought a GQ Patrol with the TB42. So far on this tank of premium i have done 220km and the needle is sitting just above 1/4 of a tank and its a Long range fuel tank. :( Boo Barry!

[Agronaught]

One hint I learnt in the TB48... don't 'underdrive' them.

I was consistently driving below the powerband for the engine (~2400rpm) and the economy really sucked, choose the right gear to keep the revs up (>3Krpm) and the performance improved considerably.

Don't get me wrong, its still a thirsty bugger but it did help.

Nah not good at all I would of thought 350 would be nearer the mark maybe more , does your model have a MAF sensor at all
Might be time for either a dyno or a damn good service
