Use E85.

Did you know that there are over 6 million flex fuel vehicles on the road in the US? Flex fuel vehicles are designed to run on either gasoline or an 85% ethanol/15% gasoline blend called E85. Although flex fuel vehicles may seem like a relatively new concept, the first one was a 1908 Model T Ford. So they've been around a while. Unfortunately, many people don't even know they own a flex-fuel vehicle so you can bet they're not using E85.

Using E85 in your car or truck creates less pollution and decreases reliance on imported and domestic oil. So if you have an flex fuel vehicle, consider fueling up with ethanol. "But where can I buy E85?" you ask? Just visit afdcmap2.nrel.gov/locator, select the alternative fuel you want, enter your location, and you'll get a list of the stations near you. There are almost 700 of them around the country. Learn more at e85fuel.com.

And if ethanol's not your thing, try fueling with biodiesel or WVO, or drive a hybrid. Whatever vehicle or fuel you choose, remember to drive gently. There are lots of ways you can help reduce air pollution. Happy travels!

"There's simply no two ways about this fuel question. Gasoline is going - alcohol is coming. It's coming to stay, too, for it's in unlimited supply. And we might as well get ready for it now. All the world is waiting for a substitute to gasoline. When that is gone, there will be no more gasoline, and long before that time, the price of gasoline will have risen to a point where it will be too expensive to burn as a motor fuel. The day is not far distant when, for every one of those barrels of gasoline, a barrel of alcohol must be substituted." - Henry Ford, 1916
