Ethanol is a grain alcohol that can be blended with gasoline and used in motor vehicles. Many gasoline stations provide a blended fuel, which typically is 10 percent ethanol and 90 percent gasoline. Vehicles do not need any modifications to use this blend of fuel. Flex fuel vehicles, which have modifications to the fuel systems, can use E85, which is a blend of up to 85 percent ethanol and 15 percent gasoline. With the modifications, these vehicles can use straight gasoline or any blend of ethanol up to 85 percent.
