About E15 (Unleaded 88)


Unleaded 88, also known as, E15 is a higher-octane fuel made from 15 percent ethanol and 85 percent gasoline. Unleaded 88 provides a slight boost in octane for your engine and contains just 5 percentage points more ethanol than 87 octane Super Unleaded E10, the most commonly used fuel in the nation.

Unleaded 88/E15 is approved for all 2001 and newer vehicles which makes up about 9 in 10 vehicles on the road today. Even better, it's often sold at a three to 10 cent discount to Super Unleaded, meaning it's not only better for the environment, it's better for your wallet, too!
