Question 4" lift with 35" tires - MPG

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?

Look to lose at least 4 MPG with big meats and a lift.

Get intake and exhaust improvements for other reasons. They will not help you MPG. That's gas engine thinking.

20 MPG is very good for your configuration.

4.10s & 20mpg with stock tires?
What speed are you going?

If you have 4.10s I'd say by all means go for 35s & see what happens. I will one of these days as well.

I go 60 on the hwy and 70 on the interstate. The speed limits are 55 on hwy and 65 on interstate, so its not like I am going slow. I will top off the front tank today and do the milage agian since its been about a year or so since I have done it.

Re: 4" lift with 35" tires - MPG

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.
