If you were actually getting 14 km per litre, I would have that truck gold plated. I'm getting between 7.5 - 8.5 in the summer and 5.5 - 6.5 in the winter. Your numbers work out to 33 miles per gallon. Never heard of a 6.0 getting that kind of mileage. 2.4 km per litre does sound very low. Probably like 7 or 8 miles to the gallon. I think normal is anywhere from around 12 to 19. Some guys say they get 20+, but those are the few.

Your numbers are about right.

I do slightly better by driving very slow.

Even if you corrected the tire size properly on the readout...

The 12" lift is probably good for a 1-3mpg penalty.
