Flex-Fuel Vehicles (FFVs) are designed to run on gasoline or E85. E85 is a blend of 85% ethanol and 15% gasoline. FFVs have been produced since 1998, and more and more manufacturers enter the market all of the time. You may own a FFV and not even know it. To determine if your vehicle is an FFV, check the inside of your car's fuel filler door for an identification sticker, yellow gas cap, or consult your owner's manual.
There are more than 15.5 million FFVs on American roads that are designed and warranted to run on ethanol blends higher than 10%. Automakers such as General Motors, Saab, Volkswagen, Ford, Lincoln, Mercury, Mercedes Benz, Isuzu, Mazda, Chrysler, Toyota, Bentley, and Nissan all offer various models equipped with flex-fuel technology.
