Look at the gas filler; you'll find the manufacturer's recommendation for fuel there, or it's in the owners manual. If it specifies Octane 91, 87, or E10 or E15, you shouldn't use anything else. Only if it says Flex-Fuel E85, should you use fuel with an Ethanol content higher than 10%. Ethanol is a corrosive and high amounts WILL harm the fuel system.

Only if your car says E85 is OK. Is it a Flex Fuel car?
