Mine.
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.Originally Posted by jaxt
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.
What exhaust system do have as mine seems to be choking up a lot

I have a standard exhaust system on my GU but YNOT is a bit of a Guru on this Forum and he might fill you in on Exhaust systems
Just note that Tony is away for three days and may only be on intermittently when he gets the chance!
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.

I've got a 99 GU 4.5L on gas, arb bull bar, snorkel, scrub bar, draw system and roof rack running 31" AT's around the town and normally average 29L/100km on gas and 22L/100km on petrol. Sounds ball pack with other 4.5L gas users. Has anyone got any tips on inproving fuel economy - short of; maintaing tyre pressure and reducing the weight of the vehicle?
Cheers

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
