MPG/lift question

Just wondering if 11.8 mpg is normal for an 03 F-250 6.0l riding on 35" general grabbers. As far as I can tell the engine is stock aside from the cold air intake. If so would re-gearing improve my mileage or would this just raise my rpm's on the freeway reducing my mileage? Also I was wondering how to tell how much of a lift is on the truck. It doest seem to be as tall as my friends truck which has a 6" lift but its definately not just a leveling kit. Thanks!

Measure from the center of the hub to the top of the wheel arch and compare to the same measurement on your friends truck. That mileage is pretty close to what I get around town with mine wiht 4.5", 35s and tuned.

I have a 45 min drive to work everyday so Im definately easy with the gas and on the freeway I drive 65mph and thats how I've been getting 11.8. When I do 70-75 mph my mileage drops about 1 mpg. I'm bring to figure out if gearing will help out at all.

Hand calculated. The best I ever got was 12.9 mpg. From most of the reading on these post it would seem my highway mpg should go up if not stay the same as stock. Starting to wonder if I have an issue with the motor.

I get about 12 in the city. So I'd say you're normal.
