Over 15mpg? Nice.
18.8mpg much?
I know how I'd rather piss away gas money![]()
Best 18.8mpg ever![]()
Does he have to drive the car at 150mph to get that mileage? With 7.3 liters in the engine I would think that low speeds <60 would get horrendous gas mileage whereas 100+mph would actually get better mpg, or do I just not know how cars work?
