Hey guys, there probably is already a thread on this but here it goes anyway.
I seem to get really bad gas mileage with my 1st gen 4cyl 2.7l engine I am running at around 5.1km/l which is around 12mpg. I think I should be running around 20 mpg or 8.1km/l. Anyone else having this problem? anything I can do better, to the truck itself, not my driving, that could help ? I will start driving like an old man to see if it will help anyways. any help would be appreciated!!
