Ethanol and your vehicle

Ethanol is a clean, high-octane, high-performance fuel for your vehicle.

Up to a ten-percent blend of ethanol is covered under warranty by every auto manufacturer that sells vehicles in the U.S. for every make and every model of vehicle.

Ethanol, the clean fuel: Ethanol is a clean-burning fuel that reduces carbon monoxide and hydrocarbon tailpipe emissions. Ethanol contains 35% oxygen by weight, making it burn more cleanly and completely than gasoline. E85 has the highest oxygen content of any fuel available, making it burn even more cleanly and even more completely than any other fuel. E85 contains 80% fewer gum-forming compounds than gasoline. Ethanol, the high performance fuel:
Pure, 100% ethanol has an octane rating of 113. Adding 10% ethanol to unleaded gasoline raises the octane by 2 - 3 points.
