What is Flex Fuel?

Answer:
Flex fuel vehicles can run on both gasoline

and E85, a mixture of 85% ethanol and 15% gasoline. Ethanol is a type of liquid fuel derived from corn and other grain crops. E85 burns cleaner than conventional gasoline and reduces both air pollution and oil dependency.

Most auto companies offer flex fuel versions of their most popular cars and trucks. Flex fuel vehicles are sold mainly to fleets and government agencies, although they are widely available to the public. These vehicles are identical to their gas-only counterparts parts in every way except for certain engine components.
