94-300

Hi, just joined the forum now that I'm finally getting my truck going.
I have a 94 f150 and I am wondering what MPG the truck should be getting. It has the 300 engine, 3.31 rear end, m5r2 trans (getting a new trans because 3rd is out and 4th is going), 30x9.5x15 tires, and its a 2wd truck. Also, I live in Florida where the roads are flat and straight.

Thank you

I had a 93 F150 with the same tranny as yours but with a 3.08 rear end. I was getting mid to upper teens with it mixed.
