Gasoline explained Use of gasoline

Gasoline is the main U.S. transportation fuel

In 2021, Americans used about 135 billion gallons of gasoline, including 134.83 billion gallons of finished motor gasoline—or about 369 million gallons per day—and about 0.18 billion gallons of finished aviation gasoline. Motor gasoline is one of the major fuels consumed in the United States and is the main product that U.S. oil refineries produce. Most of the finished motor gasoline sold for use in vehicles in the United States is about 10% fuel ethanol by volume.
