Gas Mileage

[FordSVTFan]

How is your gas mileage on your HD Supercrew.

I dont know what it is but I put one tank through it and it seems that I barely got 10 MPG while my Lightning with a lot more power and driven faster has been averaging 13 MPG.

this is somewhat on the same topic, maybe you can answer it. if an L is driven easily can it be comparable in fuel consumption to a 5 litre?
i figure my car gets about 13-14mpg. although less power and less weight.
