I have a 1996 f-350 7.3 single cab and standard transmission, does anybody have an idea of what kind of gas mileage i can get. All stock other than a flat bed and 35's.

 

With 4:10 rear, 16. With 3:55's 18 on long trips, couple MPG's less for short drives.

 

I was getting about 19-20MPG consistent with 4.10s, automatic, stock size tires, 6637 intake, 3" downpipe into 5" straightpipe, & a six switch tuner on the 75HP setting. This was all highway driving cruise control set at 75MPH for about 10,000 miles.
