What is a FlexFuel Vehicle (FFV)?
FlexFuel vehicles (FFVs) are capable of operating on 100% gasoline, E85 (85% ethanol, 15% gasoline), or any mixture in between. FFVs contain an upgraded fueling system (computer chip, fuel line, and fuel tank) which is made up of higher quality components to accommodate the higher oxygen/alcohol content of E85. FFVs are under full warranty from the manufacturer. E85 should only be used in ethanol-capable FFVs.
