Right now I am getting 20 mpg with my totally stock 1996 F-250 4x4 regular cab. If I add a 4" lift and 35" tires, how far will my mpg's drop? I am hoping not more than down to 15 mpg. If I were to add a tymar intake and a 3" down pipe leading out to dual 6" stacks, could the mpg increase?
A couple of weeks ago I drove about 165 miles (nearly all highway) and hand-calculated just above 18.5mpg. This was with me babying it as much as possible and keeping the speed between 65-70mph.
With "normal" driving (75ish mph on the highway) with a mix of some city driving, I have been averaging about 16mpg on a tank of fuel with my setup.
my sister has a 96 ex. cab long bed with 3in's and 35's with a manual and it gets about 15-17 on the interstate, and its stock other than exhaust, but were gonna change that pretty soon..
