Mileage difference between F-150 and F-250

[fabsroman]

I have the F-350 Lariat in crew cab with the diesel and I have been averaging a little over 15 mpg all around, with the majority of the miles being on the highway. Now, I know this is a completely different truck than what you are asking for, but my truck has a computer readout in it that tells me the mpg I am getting while I am driving it along with the miles to empty. I would guess that a F-250 would also have this. Mine is located on the ceiling right between the driver's and passenger's side. So, if you have a dealership near you, look for an F-250 with a mileage computer in it and take it for a test drive.
