FFVs are widely available. As of 2005, the National Ethanol Vehicle Coalition estimated that approximately 5 million FFVs have already been sold in the United States, although many buyers remain unaware that they may fuel with E85. Check your owner's manual, visit with your dealer, or see our list of current model year FFVs to determine if you drive a vehicle that can fuel with E85.
E85 fueling stations are located primarily in the Midwest; more than 150 public E85 stations are available across the United States. The actual fueling process is the same as fueling with gasoline or diesel. Visit our station locator to find the stations in your area.
FFVs have recently become widely used by consumers, but they have operated in private and government fleets for years. Take a look at our Clean Cities fleet success stories for details.
Vehicle and Fuel Costs
E85 is usually sold at prices comparable to regular grade gasoline, although prices vary regionally. For more information on fuel prices, download the Alternative Fuel Price Report.
With the mass production of some E85 compatible vehicles, original equipment manufacturers usually offer these vehicles at the same prices as comparable gasoline vehicles. In some cases, E85 compatibility is offered as a vehicle option at a slight cost increase to the consumer.
Use of special lubricants may be required for FFVs. Check the owner's manual or consult with the manufacturer to ensure that the correct engine oil is used. Use E85 replacement parts (identify E85 as the fuel when ordering). Maintenance assistance is available from local dealers; practices are very similar, if not identical, to those for conventionally fueled vehicles.
Compared with gasoline-fueled vehicles, most ethanol-fueled vehicles produce lower carbon monoxide and carbon dioxide emissions and the same or lower levels of hydrocarbon and non-methane hydrocarbon emissions. Oxides of nitrogen (NOx) emissions are about the same for ethanol and gasoline vehicles. E85 has fewer highly volatile components than gasoline and so has fewer evaporative emissions.
Ethanol is domestically produced, so its use helps reduce the nation's dependence on imported oil and can help boost the agricultural sector's economy. In addition, it's a renewable fuel made from domestically grown crops like corn, sugar beets, sugar cane, barley, and wheat. Currently, increased R&D efforts are being conducted on the use of cellulosic biomass, such as corn stover, switchgrass, and other bio-feedstocks for the production of ethanol.
General Motors has a fun "Cornulator" on its Live Green, Go Yellow Web site. Use it to estimate barrels of oil saved by fueling with E85.
Ethanol is a high-octane fuel and has 80% or more of the energy content of gasoline. Some auto manufacturers are installing larger fuel tanks, so the range of FFVs is similar to gasoline vehicles. Power, acceleration, payload, and cruise speed of vehicles operating with E85 are comparable to those operating with equivalent conventional fuels.
