Ethanol is a renewable fuel made from various plant materials, which collectively are called "biomass." Nearly half of U.S. gasoline contains ethanol in a low-level blend to oxygenate the fuel and reduce air pollution. Ethanol is also increasingly available in E85 (a high-level ethanol blend) for use in flexible fuel vehicles (FFVs). Studies have estimated that ethanol and other biofuels could replace 30% or more of U.S. gasoline demand by 2030. Regionally, E85 FFVs comprise over 60% of the alternative fuel vehicles on our roads.

Flexible Fuel Vehicles (FFVs)
Sold by all U.S. vehicle manufacturers, flexible fuel vehicles are capable of operating on gasoline, E85 (85% ethanol, 15% gasoline), or a mixture of both. There are more than 6 million flexible fuel vehicles on U.S. roads today, but many owners don't know their vehicle is one. Visit the 2017 Model Year Flex Fuel Vehicle Guide to see if yours is one.
