Average 14 in summer with 13 avg in winter. I try to use Shell or BP gas. Its a mixed commute, with hills, highway, stopsigns and mixed speeds. Tonneau cover, general grabbers, gotts, superchips and kn filter maeby got me 1 mpg. Full grill guard and 2" leveling Im sure did not help. Still love my truck.

Wow guys! You guys are getting great mileage compared to my 04 SCab 5.4. I am averaging 9! Yes I said that right, 9!! The best I have gotten is 11 and I have a tonneau and no extras. I want to get a cold-air intake and a chip but I am worried that it will get worse if I do that.

I think the major issues would be: alignment, tire pressure, lift, map or O2 sensors?
I have a griffin "chip" and improved mileage by 1 or so. (set it to lockout tc in 3 rd at a slower speed for city driving.)
