Mine is a 2009 with 285/75 mud tyres 4" lift. Bar, drawers, winch etc and roof bars. I drive from Perth to Albany twice a week. It has a BAS remap, intercooler etc. Around town I get 12's and on the run to Albany I get between 13-14's. Up to 100kmh is OK but 110 or over uses more juice. We are pushing bricks through the air remember. I usually sit at the 110kmh end of the scale

If you do a lot of stopping and starting which involves a lot of first gear use the fuel consumption does suffer. I have two 2.4 Puma's and both do significantly better fuel consumption wise on long journeys at 80 - 100 kms.Quote:

I will get 500km out of a tank. Might be lucky to get 530km's.
On long trips I wouldn't get over 105kms, but average a 100km's easy.
A modern engine should be able to do 105km's/hr efficiently I think.
I monitored instantaneous fuel consumption today with Ultragauge. on 2.2 130
On a flat road at a steady 100 k/h : 5th gear the value stabilised around 11 litres/h
6th gear used about 9 litres/h
To get stable readings I had to drive the throttle very carefully. Since I dont usually make careful adjustments intentionally the values are probably lower than "normal" driving
It's the box shape that determines fuel use not the motor,I feel the TDCi uses more fuel simply because the extra performance allows for higher speed. PatQuote:

I made a point of filling before leaving to track the fuel usage. I knew it was bad but nearly fell over when I did the figures on my return.
Any clues? I have been contemplating tweaking it. This trip will help my cause.
Pure arsed guesses:
Trailer brakes not binding or other defect?
In too high a gear and engine lugging. I imagine with 2 t behind you want max torque, rather than min revs.
Good luck
I think you need to check that figure,around 14 per 100 is about right for that type of driving,or you have a hole in the tank.Mine did 542k's with 58ltrs this weekend. PatQuote:

Bad maths?Quote:
