I am looking at new F250, I have f wheel about 8000lbs. I would like to know gas mileage while towing and not towing, also on diesel. How would gas handle the load? Thanks
The diesel peaks in both horsepower and torque at almost the same RPM (usually around 3K in motor vehicles). Gassers peak torque at about 1800, but the horsepower doesn't build up until much later in the curve.
The total explanation is, of course, much more complex but that is the basics.
