FFTEX says:You know what half of those tips there if you utilize them you have no business driving a truck. If you lift your truck or have the big wheels on it you generally should not be driving it every day if you want to save fuel.
The biggest tip for saving fuel is get out of the truck and into a 4 banger car.
It is still a good list though. My problem is neither of my trucks have cruise control and the 86 doesn't even have AC. The 97 the AC doesn't work.
