ill throw something in here
power required to push the car along is a cubic function of the velocity.
so if you double your speed you need 8 times the power to maintain that speed.
I drove a 97 gxl awd Cruzer petrol 10000KM round trip towing a 14 Tinny with a heavy duty trailer.It had a 300L long rang tank combined, with the typical mods,Bull bar,kamar rear+33's.
We never got over 1000k's out of a tank.
The next year we did the same trip my GU2 3ltd and got 1000k's + form a 110Ltr tank.
Petrol Cruzers and Patrols are savage on fuel.
Buy any late common rail diesel and you will never look back.

Non turbo diesel cruisers are no better.
Easy 20L+/100km while 'cruising' at 110kph.

Hey Brett you sound like my mate chris lol.
from what little understanding i have if you can match peak power with cruzin speed you will have a economical car.
Eg a LS1 power holden just ticking at 110kph(9l/100km)
V the 3.8 auto reving at freeway speed is around 8l/1000km.
Freeway speeds and 4wds never end up very good due to the huge drag factor.
I got an extra 110km per tank on my Hilux just by changing the tray for a tub.
case
fwiw: tonneau cover over the tray of my style-side ute (01 hilux twin cab) seemed to lessen drag (and possibly improved fuel use). Seemed fairly obvious when I saw drag racing utes lowering the tailgate to improve rear grip.
Its a tough call for drag racing utes between the extra rear grip acheived by lowering the tailgate, but at the same time increasing drag.

agreed - i was thinking about this after posting ...in the US craftsman series where they race silhouette trucks they effectively have a tonneau cover. At the drag's, the modern boganutes are invariably have a hard lid - but the older utes either have a flat tray with no sides or a side-style body with the tray down.
I presume the thinking is: no cover turns the tray area into an enormous air-bucket, drop tailgate eliminates source of drag. Assuming there is positive pressure above not below the tailgate, the extra area behind the rear axle levers weight from the front to the rear ... hypothetically?

in that case i my thunking was obviously wrong. So next time i see this at the drags I will laugh and point.
TurboRA28: sorry for the post hijak![]()
Yep, An "Air Pillow" formed in the tray. Coming over the roof, down to the height of the closed tailgate and then back towards the back of the cab and up into the stream of air coming over the roof.
So rather than air coming over the roof and hitting the closed tailgate creating drag. It forms the pillow and air coming over the roof goes back and straight over the top of the tailgate.

25 lts per 100ks is shocking ive never heard of such bad fuel usage. We were complaining at work that our 2.4 rodeo ute only gets 350 k's out of a 70 litre tank untill this post that was the most ive heard of. As for any help reguarding your fuel usage im stuck.
my work rodeo is a 3.5 v6 and does around that or a bit better
what size tyres are on the bus?
what style of tyres are on the bus and the 4wd?
swap motors from one to the other, milages will likely end up being similar as what they are now.
big heavy tyres and drivelines, and gearings that just dont seem to work are what will be killing your fuel consumption
