E85 is a high-level gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season (see Fuel Properties and E85 Specifications). It is considered an alternative fuel under the Energy Policy Act of 1992 (EPAct) and can be used in flexible fuel vehicles (FFVs), which are commonly available from domestic and foreign automakers. Use the Vehicle Cost Calculator to look up FFV fuel economy, fuel costs, and greenhouse gas reductions.
Other than lower gas mileage, motorists will see little difference when using E85 versus gasoline. E85 has about 27% less energy per gallon than gasoline (mileage penalty lessens as ethanol content decreases), but, because ethanol is a high-octane fuel, it offers increased vehicle power and performance.

There are more than 2,400 U.S. fueling stations that offer E85 to the over 10.6 million FFVs on U.S. roadways. E85 is available in more than 40 states, with a concentration of stations in the Midwest. Find E85 Fueling Station Locations near you.
