Ethanol
Ethanol is a renewable fuel made from corn and other plant materials. The use of ethanol is widespread, and approximately 97% of gasoline in the U.S. contains some ethanol. The most common blend of ethanol is E10 (10% ethanol, 90% gasoline). Ethanol is also available as E85 (or flex fuel)—a high-level ethanol blend containing 51%-83% ethanol depending on season and geography—for use in flexible fuel vehicles. E15 is defined by the Environmental Protection Agency as a blend of 10.5%-15% ethanol with gasoline. It is an approved ethanol blend for use in model year 2001 and newer light-duty conventional vehicles.
