This site is intended to help you find E85, ethanol and Flex Fuel information on the Web.

Make sure to visit the Articles Section to find more information. E85 is an alcohol fuel mixture of 85% ethanol (ethyl alcohol, i.e., grain alcohol) and 15% gasoline (proportioned by volume rather than mass) that can be used in flex fuel vehicles.

It is a clean-burning, domestically produced, renewable fuel that contributes to decreased dependence on imported oil. Automobiles called flex fuel vehicles are designed to run on E85.

Ethanol fact: American farmers produce an overabundance of food for the world's consumers and livestock, and ethanol is produced from excess corn that would have otherwise been exported.

The majority of the ethanol in the U.S. is made from corn, but it can also be produced from other feed stocks such as grain sorghum, wheat, barley, or potatoes. Brazil, the world's largest ethanol producer, makes the fuel from sugarcane.

E85 is best used in engines modified to accept higher concentrations of ethanol or ethyl alcohol. Such flex fuel engines are designed to run on any mixture of gasoline or ethanol or ethyl alcohol with up to 85% ethanol by volume.

The primary differences from non flex fuel vehicles is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system, the use of fuel pumps capable of operating with electrically-conductive (alcohol) instead of non-conducting dielectric (gasoline) fuel, specially-coated wear-resistant engine parts, fuel injection control systems having a wider range of pulse widths (for injecting approximately 30% more fuel), the selection of stainless steel fuel lines (sometimes lined with plastic), the selection of stainless steel fuel tanks in place of terne fuel tanks, and, in some cases, the use of acid-neutralizing motor oil.
