E85 is a term that refers to high-level gasoline-ethanol blends containing 51% to 83% ethanol, depending on geography and season (see Fuel Properties and E85 Specification). It 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 driving FFVs will see little difference when using E85 versus gasoline. Depending on the actual ethanol content, E85 has less energy per gallon than gasoline to varying degrees (mileage penalty lessens as the ethanol content decreases), but, because ethanol is a high-octane fuel, the ethanol blended fuel offers increased vehicle power and performance.

E85 Stations

There are more than 2,400 U.S. fueling stations that offer high-level ethanol blends to the over 12.8 million FFVs on U.S. roadways. The high-level blends are available in more than 40 states, with a concentration of stations in the Midwest. Find E85 Fueling Station Locations near you.
