Mileage difference between F-150 and F-250
 

Was wondering if anyone knows what a 5.4 V8 F-250 gets mileage wise? I know the 5.4 F-150 gets 18mpg on the highway, but they don't list mileage numbers on the Super Dutys.

Thanks,

Billy

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.
