E85 is a blend of 85% ethanol and 15% gasoline. It is the most commonly available blended fuel for use in flex-fuel vehicles (FFVs). Ethanol is a corrosive alcohol that will degrade common steel and rubber fuel system parts on conventional vehicles. Flex-fuel vehicles are manufactured with synthetic and/or composite fuel system parts that can tolerate high levels of alcohol.
