What is E15 Fuel?

The Renewable Fuel Standard, included as part of the Energy Independence and Security Act of 2007, requires the use of increasing volumes of renewable fuels (e.g., ethanol, biomass based diesel) in gasoline and diesel sold in the United States.

Most of our Exxon and Mobil branded gasoline currently contains 10% ethanol, also known as E10 fuel. In 2011, the US Environmental Protection Agency (US EPA) approved gasoline blends containing 15% ethanol (E15 fuel) for use in flexible-fuel vehicles and in model year 2001 and newer gasoline cars, light-duty trucks, and medium-duty passenger vehicles (SUVs). Since then, automobile manufacturers began to warrant new vehicles for gasoline blends up to 15% ethanol and E15 volumes are increasing in the marketplace. Refer to your owner’s manual to confirm your vehicle’s requirements.
