Ethanol & Your Vehicle

Benefits of Ethanol Blends

Millions of Americans have driven billions of trouble-free miles using ethanol-blended gasoline over the past quarter century. The majority of this gasoline has been E-10 Unleaded, a blend of 10 percent ethanol and 90 percent ordinary unleaded gasoline. However, E85 (85 percent ethanol and 15 percent ordinary gasoline) is rapidly becoming an important part of the nation’s fuel supply.

Approved for use by every major automaker in the world, E-10 Unleaded provides a number of benefits for drivers:

  • Additional octane: The ethanol in E-10 Unleaded adds two to three points of octane to ordinary gasoline, helping improve engine performance.
  • Cleaner fuel injectors: Ethanol helps prevent the build-up of power-robbing deposits in fuel injection systems.
  • A gas line antifreeze: Ethanol suspends moisture in the fuel systems, eliminating the need for gas tank additives in cold weather.
  • Cleaner air: Ethanol reduces toxic emissions in engine exhaust, helping keep America’s air cleaner.
