Diesels are the way to go. My '86 Ford Ranger with Mitsu 2.3TD gets 38mpg on the highway. My wife's 3/4 ton '97 GMC Suburban 6.5TD 4wd got 22mpg on the drive home from Naples, FL a couple of weekends ago. The PO verified he got the same mileage driving it from Maine to Naples two weeks beforehand. (3.42 rear) He towed a car on a tow dolly for part of the trip and still got 19mpg.

Diesels extract more energy from petroleum than gas burners. They will also run on a variety of fuels and blends.
