TD42t economy

[Alitis007]

Just curious what sort of economy the td42t's get after seeing the meet up in the middle thread. I would like to know what they get around town, on the highway etc

[Winnie]

I normally get around 13L/100 just driving around but lately has been about 12L/100
Fully loaded on the Simmo trip I was getting 15L/100

[Alitis007]

And your running your 33's all the time yeah winnie??

[Clunk]

I get on 14l/100 on average, that's running on 33s, mix of town/highway/offroading

[Winnie]

And your running your 33's all the time yeah winnie??

Yes I am now.

Thinking of getting a diesel George?
Or turbo the Ti ?

[nissannewby]

I get 12.5-13/100 with 33's. 14-15/100 with the canopy on.

Before I modified it the best I got was 10.5/100 on 265 highway terrains.

[mudski]

Feck! Those figures are on par with my ZD30!!!!

[threedogs]

265s will give you great fuel figures , downside is your Patrol looks like a skate board

[macca86]

Just did my first full tank mixed driving on 33's 14.6 L per 100km must say being a little heavy footed as it's only been my car fir 2 weeks

[mudski]

I think of it more like a pregnant roller skate :)

[threedogs]

yours would look so wrong lol

[Clunk]

They don't look to out of place on a GQ with only a 2in lift.

I forgot to mention mines turbo only, no intercooler fitted yet

[AB]

Comparing zd30s up at the simmo we were close on par Mark.

[Ben-e-boy]

When I bought mine NA I was getting 10.8L/100. When I turbo'd it 13psi unintercooled , stock pump 120rwhp it rose to 12.4L/100, next tune same turbo, W2A cooler 12mm pump 207 rwhp it dropped to 11.5L/100. Now with a new turbo same cooler, pump etc it has jumped to 15.4L/100.

I can drop this though, my pump was set up for the old turbo, tune etc, and the new turbo boosts higher at highway speeds. It is over coming the compensator spring so I am almost dumping in full fuel.
If I get a new compensator pin and change the spring, and try and get more travel out of the pin I should be able to grind a new pin profile and regain some fuel efficiency

Especially with factory flares =)

[SonOf]

Was getting 12/100 on 265,s. Just uped the wheels to 285/75's so will see how it goes. Do mainly highway driving

[Alitis007]

I don't know what i'm thinking any more lol.......

[Alitis007]

Thanks everyone for your replies, it certainly is making me second guess the original conversion i was going to do.

[kevin07]

Feck! Those figures are on par with my ZD30!!!!

what do you mean feck there on par with a zd30 there all better than what I get. the reason I got a zd was for fuel economy after talking to a few blokes the best they were getting was 18 to 20 from there 4.2s. all I can say is faaaaaark me dead said forskin ned the old bastard from the bush.

[Irish]

Best of both worlds George, twin turbo V8 diesel!!!

[threedogs]

I think Marks have adaptor plates/kits for a Viper V10 conversion.
Instead of changing your motor why not think about doing a Portal axle swap,
combined with two diff locks would see you go many places normal 4x4s couldn't

[Alitis007]

Your too generous Pete, thanks for funding that little project!

Yeah but the problem is getting to those places without using a tanker full of fuel haha

[Irish]

I'll get my tools and meet you at Crown carpark, hahaha

Well funny you should say that. The duramax conversions getting around are getting figures between 12-14/100. 400hp and 1000+nm of torque from a turbo 6.6 v8 commonrail diesel what's not to like :).

Have said that we can modify a TD42 to produce in the area of 300hp and still get 15/100 or less.

[Alitis007]

Done!!! Geez your a top bloke taking me out to lunch aswell!

Realistically talking with our hands off our bollocks lol, i don't need that sort of power. I like to build my cars to be used thats why i have a toy to thrash around. I need to make the trol practical and reliable for how i use it which is towing the boat ( a bit over 1t) and a trailer full of firewood ( around 2t), wheeling is a bonus.

To put it into perspective a duramax conversion would be around 35k, a td42 and ls1/ls3 10 - 15k. Personally i aint spending more than 10k on my trol hahaha!!

I'm getting those figures now what the TD boys are getting. Or there abouts... I would have thought they would be worse...

[Clunk]

Don't forget that the figures given so far are from lighter GQ's. I drive Miss Daisy and rarely give it some unless needed (on sand), most hwy driving I tend to stick around 100kph as that seems to be the sweet spot on my td42.
Now driving the tb42, that's a different kettle of fish all together, crap economy no matter what, where or how I drive so it's foot down and go :D

[macca86]

My 14.6 l/100 is from a 2005 td42i wagon with 280 000km on the clock this next tank is looking at mid 13's as I haven't been getting up her.

[nissannewby]

Yep mine are also from a 2004 TD42Ti with 330k on the clock still on original injectors and pump running 25psi.

[SonOf]

Mine is a 99GU but I drive like an old b@stard these days and am not too heavy on the pedal. I have very little to no traffic and roadsmare 80 to 100 kmh for 90% of the run. I alternate between adding 2 stroke oil in one tank, followed by injector cleaner each 20k. Not sure that helps but it keeps the girl a little cleaner.

Also the best figures shown by Bene and Matt are utes which 'should' be lighter but also are modified

[Ben-e-boy]

The uts arn't that much lighter, when I bought mine full of fuel with me in it it was 2.6t

[Alitis007]

Maybe you need to lay off the krispy kremes Bene lol! :D

[Ben-e-boy]

Maybe you need to lay off the krispy kremes Bene lol! :D

I was much lighter when I bought it

[nissannewby]

Yep last time I put mine on the weigh bridge with an empty tray, 2 occupants and half a tank of diesel it came back at 2.7t

[PMC]

G'day Alitis,

I have got a 2001 GU 4.2 turbo diesel Patrol wagon and I get 13 litres per 100ks with 2inch lift, steel full length ARB roof rack, with all the bells and whistle's on travelling on all-terrain 33's.

With my trip down to Victoria at Christmas time fully loaded with my wife and three children, aircon on and sitting on 110ks, I was getting between 16-17 litres per 100ks.

Regards,

PMC

Wow! Fully loaded under the same circumstances my TB42 gets 20-24L per 100km (depending on terrain). That's really surprising.....

Mind you I can get nowhere near those unloaded figures while just tooling around in it.......like Clunk suggested, it doesn't seem to matter how I drive it.....it's always thirsty......Anyway, play on......

Could it be coz the steel tray is thicker and heavier than the back end of a wagon ??

[Alitis007]

Thanks again for everyone's input and i hope i get more replies so i can get a more accurate average of fuel consumption of these motors not only for myself but to others thinking of converting to a TD42

[Ben-e-boy]

Yeah, mats has a steel checker plate floor with 5th wheel attachment and mine is hard wood, much heavier than sheet metal

I can carry 220L of diesel too.

[Patrol 1993]

Hi Alitis007,

I am a new member. I have a 1993 Patrol GQ II ST TB42E
I have been told as you increase the diameter of your tires your fuel economy gets worse.
What size tires do you think I should get.

What is the difference between a td42t's and a TB42E, is the td42t's a turbo diesel. Mine is a 4.2 injected petrol.

[Alitis007]

Increasing your tyre size only increases fuel consumption if you try to accelerate at a faster rate than normal, if your using your trip meter / odometer to calculate fuel consumption larger tyres will show a lower distance travelled because a 33"(285/75) tyre has a larger rolling distance than a 30.5" (265/70), so one revolution of the 33 will take you further than the 30 thus making it calculate to a higher fuel consumption coz of the lover odometer reading. Tyre size is totally up to you coz you need to work out what terrain you drive on and what you use your car for. The main difference between the tb42 and the td42 is like you said, one is petrol and the other is diesel.

[Ben-e-boy]

The td42's are much much better than the tb42's too. Thats the biggest difference :p

[liftlid]

Just did the Simpson crossing east to west my td42 got 19.5 lt per 100. The tb42 got 26 lt per 100 on petrol, for the rest of the trip I got between 16 and 17 lt per 100, dirt and bitumen, these cars both were fully loaded and roof racks. Unloaded city/ hwy I'm in the 13/14 lt range

Thats on 35's yeah??

[HuskyInAuz]

Around town and short trips <3 hours from Jervis Bay to Canberra 13.2 on 265 TOYO HT's ..

Heading north in two days towing a small CSU (Camping Support Unit) will post as I'll fill up at Costco in Casula, NSWand then again in Brisbane.

[liftlid]

33" with 4.6 diffs on gq
31" with 4.1 diffs on mav

That would be great! How heavy is the camper do you think ??

For some reason i thought your where running 35's... Never mind mate, thanks for the info anyway!

[liftlid]

35's in the high country that's why I have 4.6 diff gears, so I'm under geared with the 33's and could possibly get better economy on long runs at 100 kph

[nissannewby]

I have just fitted 35's to mine once I have used the tanks I will report back

[liftlid]

The 4 cyl diesels economy is on par with the 6 when heavily loaded, on the recent trip we did the hilux's best economy used 10 lt less fuel than my 4.2 , sometimes less than that, seen similar with the GU 3 lt and prados.

Just to clarify Liftlid, you are talking about ~10lt less per tank? When you were doing same K's and terrain?

Yep surprising isn't it, the cars were following me

[DX grunt]

Only measured fuel consumption once on my 2005 4.2 TDi ex Telstra ute with the pod on the back and got 16lt/100km. I'm still running cheesecutters. haha.

99.99% of my driving is on country roads and is mostly driven in a head/cross wind. It doesn't help that the pod protrudes externally of the cab, as it basically acts like a wind anchor.

That's probably why I sit on about 90k's everywhere I go. lol.

Rossco.

[HuskyInAuz]

Just did a economy check from Casula to North Lakes with a 2 hour stop and go stint in Sydney. I usually drive at or above the posted speed pulling a camper trailer and one box on the roof.
16.2L/100

[HuskyInAuz]

Okay update now that I have some reliable internet.
$145.99/L at Casula
$147.99/L Brisbane
Casula to Brisbane, 16.2 L/100 with the speedo at 110+ most of the time, only one small box on the roof rack.
North Lakes to Gympie (going up and down the hills in Mapleton multiple times) 15.9 L/100
$145.99 /L Gympie off to Emerald 100k/hr
Emerald (biggest fill up) $146.99 /L (Navigator got some cold coffee drinks for another $0.04 off per liter) 16.02 @ 100 km/hr (as close as I could keep it)
Emerald to Charters Tower with a side trip to Townsville, 16.03 (yup the same)
Charters Tower to Atherton, 16.3 (I put two storage containers on roof rack in CT) $165.99/L

[Patrol 1993]

Hi Sonof
How are those 285/75's going.
Notice any difference to fuel economy.

Thanks,

Neil.

[@GUte]

2000 GU coil cab

Aftermarket turbo/intercooler, 12mm pump, 4/6" lift, 4.3 diffs, 305 mud terrain's @ 40psi, 400k

14L/100klm.

Without trying! Mixed driving from freeway to bush.To think I would be in the 13's if I did an economy run! :thumbup:

[katwoman]

Just to add something a little different,
Fully loaded, 33 muddies, all factory under the bonnet, in sand 14L/100. Straight diesel
Running around town, I get about 11L, turn on the gas, it drops to about 9L, and I dont drive like a nana....

[@GUte]

and I dont drive like a nana....

Yes you do if it's std! :tease:

But gee, they are some good numbers!

[katwoman]

Yes you do if it's std! :tease:



That's what the gas is for !!! More Oomph. Oh, and it's better for the enviroment.

[snakey1989]

Well, I have a TB42 carbied GQ with a 350 Holley on it (don't ask)
Running 32's, 2" lift, roof racks and drawers, pulling about 2.7t;
on road (85-95kmh) I get about 19.6L/100km on ULP and 20.5 on LPG.
Fully loaded towing a 17.5 ft caravan (75-95) I get about 24 on ULP and 28 on LPG.

Just acquired a TD42T GU wagon, stealing the donk.
Will post figures when she's in!

Wonder if I can bolt the TB42 into the GU and sell it on. hmmmmmm. :-)

[nissannewby]

I have just fitted 35's to mine once I have used the tanks I will report back

Finally got around to doing this for you lol. 315/75/16 km2's managed to get 13.7/100 with a close to 200km of towing a horse float.

[Stropp]

geez thats very good, best i got on the simpson was 13 odd per 100k but worst was 15.2

What's your engine configuration Mat?

[nissannewby]

What's your engine configuration Mat?

TD42Ti, standard intercooler, modified airbox lid, 3" ss exhaust, egr deleted, adrad radiator, original injectors, original injector pump (tuned by myself), UFI 18g @ 25psi.

The old girl has just knocked over 330k she is getting tired in the fuel side of things and the above is certainly at the better end of the figures for me. It has been serviced in the last week so I think that helped.

[snakey1989]

GQ TD42T (GU Factory turbo), disconnected wastegate and had pump compensator modified to suit.
33's, 3" lift, roof racks, bullbar with light bar on top. All the nasty wind catchers.
Average 11.5 - 11.9 L/100km on longer trips. 12.5 around the Snowy Mtns.
17.5 towing a 17ft full height caravan.

Soooo stoked.

[sooty_10]

I don't like reading this thread, cause either you guys are all full of shit or my economy is :(
