[altech]

Hi Guys, Just done some figures on my 4.5 petrol , found that I'm getting 15.6 litres per 100 km's on hi-octane fuel and LPG getting 19 litres per 100 kms , these figures are OK . ? what do you think regards Alex

[threedogs]

Are these HWY figures and what size Tyres please.
When Bob wakes up he'll be able to tell you if you're in the ballpark or not. lol
Sound ok.
Tyre size is just for survey I'm doing on the side, Thanks,,,,,,,,,,,,,,TD

That's pretty damn good mate! Not many people will get better than that

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

That is about what I get out of my 98 4.5L GU
Very economical on Gas and Gas is about 58c a Litre in Bendigo at present

[Bmak]

Pretty close to what I get too.
Works cheap to drive the patrol on gas than my ba falcon on petrol

Im getting around 24 L of LPG with 31 tyres. I know guys who are getting worse out of the 4.5's

I'm getting about 20/100 on LPG. Depends on the LPG blend.

gawd, I hate these threads ...

25l/100km city/highway. 30+ in low range. New mixer, valves done, dyno and two different lpg mechanics. I know autos use a bit more but ...

16l/100km. I wish! What's your secret guys?

Try cleaning the MAF and after doing so disconnect the battery for a couple of hours

yeah pretty good. you'd be getting over 450 k's per tank on lpg if you have the same size 88 litre tank as me. id say its hwy ks as i get the same from mine in hwy with 33's. what do you get in city on lpg Alex....

jgoose, 12 lit /100 towing a trailer, that's amazing. is the car stock??

4by. All ive done to it so far is fit a k&n pod filter the one thats mounted in a cone type housing the opening was sitting too close to the windscreen washer bottle so i just used a couple of nylon tyes to hold it up level with the original air cleaner housing mounts as a temp solution as soon as i get time ill connect it to my snorkel

[lhurley]

Im getting about 25/100 on petrol, and about 22 on gas. mine direct injection with a faulty injector. With 33's and 2" lift in an auto.

[Alitis007]

Im getting 13 - 14 / 100 on the freeway and 17 - 18 / 100 city. Stock everything on 265's a/ts using 98 RON. My goal would be 9 -10 freeway and 13 - 14 city but i don't think that will happen with the 4.5, i was going to try and better my economy with an exhaust, snorkel and air filter/ box upgrade buy haven't had a chance to do anything lol.

Just returned from a Camping Trip towing a Jayco Dove Camper Van

450 K's and used 107 Litres of LPG and that is 23.87/100 K's at a cost of $64.24 and that equates to 14.276 cents per Kilometre

Thanks Bob, numbers I dream of ... btw, new maf and voltages are good.

Do you run a tank of petrol through every now and then? Do you use a valve lubricant? How often do you do the valve clearances?

thanks in advance.

Valve clearances checked every 10,000 K's
