21 mpg?!?

Borrowed a friend Excursion for a couple of weeks. It was a lifted 4x4 with 37" tires and 4.56 gears. Best I could get on the freeway with it was 6 mpg.....Was a very pricey couple of weeks...

Lol, my 1965 Fargo W500 Power Wagon, 4x4 with 40" bias ply's on split rims with 4.88's with a 440 4 speed gets about 4 MPG, so you got me beat!
