Can you believe I put corn in my gas tank, too! Ethanol is made from corn and is a fuel additive. Today, 1 billion bushels of corn are used to make 2 1/2 billion gallons of ethanol. That's a lot of fuel! Corn is also used in the tires, the plastics in my car and the paint. Gee, I'd never have believed it - Corn is Everywhere!
