Chances are you have fueled up with ethanol before! Nearly all gasoline sold in the U.S. contains 10 percent ethanol-what we call E10. Ethanol has been used in cars since the early 1900s. If you are driving a model year 2001 or newer this summer, consider pumping a higher blend like E15, also known as Unleaded 88! Driving a flex fuel vehicle? Save some money by filling up with E20, E30, or E85. Fueling up with a higher ethanol blend results in cleaner burning and less emissions being released. So, as you hop in the car on your next big adventure as a family this summer, consider fueling up with a cleaner and less expensive ethanol blend. Want to learn how ethanol is made?
