What model years? I don’t remember Ford making a 7.5L gas but could be wrong.
7.3 diesel? That’s back 20 some odd years ago. My neighbor has a 1999 F250 with that 7.3 with only 45k miles. Nice truck.
Modern 7.3L gas truck don’t get great mileage but better than gas engines of old. Definitely better than 10mpg unloaded!
