Where can you view diesel truck mpg ratings?

Fueleconomy.gov is a website maintained by the United States Department of Energy that provides the fuel efficiency ratings for most vehicles available for sale in the United States, including diesel trucks. This website provides the official Environmental Protection Agency estimate for the fuel mileage of each vehicle.

It also allows vehicle owners to post the fuel mileages they have achieved for comparison. The website is searched in a number of ways, including by vehicle class and by model. The website provides estimates for highway mileage, city mileage and combined mileage. Estimates are available for diesel-burning cars and trucks as of 2016.
