My 1982 Chevy LUV diesel that I have owned now for 4 years consistently gets 37 mpg. It is a longbed 2WD with the 5-speed transmission. The driving involves mostly town driving and on some occasions I drive over 55 mph. The fuel mileage I get is one reason why I love that truck. In the 4 years I have owned it I have never ran out of fuel and believe me I have gone past the E mark plenty of times. The thing is with these trucks is they are no horsepower machines and you have to look past that because they offer great reliability, great fuel mileage, one hell of a diesel engine, and simple, easy manufacturer designs.
