Gasoline is the most commonly used U.S. transportation fuel
Gasoline is the dominant transportation fuel used in the United States. Gasoline (excluding fuel ethanol) accounted for 56% of total U.S. transportation energy use in 2014. When the ethanol that is blended into finished motor gasoline is included, gasoline's share was about 60%. Gasoline (including fuel ethanol) consumption for transportation averaged about 8.8 million barrels (368 million gallons) per day. About 7 million gallons per day of gasoline were consumed for uses other than for transportation. Gasoline is used mainly in cars, motorcycles, and light trucks. Diesel fuel (or distillate fuel) is used mainly by heavy trucks, buses, and trains. Kerosene is used in jet airplanes, and residual fuel oil is used in ships. Natural gas and liquid petroleum gas are used in all types of vehicles, but they are used predominantly in heavy duty vehicles such as buses and other large transportation vehicles. Most of the electricity used for transportation is used by public mass transit systems.
