Most of the diesel fuel produced and consumed in the United States is refined from crude oil at petroleum refineries. U.S. petroleum refineries produce an average of 11 to 12 gallons of diesel fuel from each 42-gallon (U.S.) barrel of crude oil. The United States also produces and consumes biomass-based diesel fuels.
