How Flex-Fuel Vehicles Work

Author's Note

I don't own a flex-fuel vehicle. But I do live near Iowa, a Corn Belt state and the source of much of America's ethanol. There are plenty of gas stations in the area selling ethanol. Make sure you don't put ethanol in a non-flex-fuel car. If you do so accidentally, empty your tank and refill it with regular gas and you'll be fine.
