Which Diesel Truck Gets The Best MPG?

Manufacturers of light-duty trucks and cars, whether diesel or gas, are required to report an estimate of fuel economy to the Environmental Protection Agency (EPA). You’ll find these estimates on the window stickers of new vehicles sold on dealership lots. It’s also easy to find EPA estimates in reviews for these new vehicles. The only exception to this is heavy-duty (HD) trucks. Manufacturers of trucks with a gross vehicle weight rating of over 8,500 pounds are not required to report fuel economy estimates.

When it comes to the best MPG for a diesel truck, you’ll generally find it in newer light-duty pickups with the smaller versions of Cummins, Powerstroke, and Duramax diesel engines. In general, the lighter the truck the better fuel economy it usually has. This means that 2WD versions of any given truck model usually get better MPG than its 4WD version.
