Higher Quality At A Lower Price

We know drivers look for savings when they purchase fuel for their vehicles. E15 is a high–quality fuel that contains 15 percent ethanol and 85 percent gasoline, resulting in cost savings for Americans at the pump. E15 also burns cleaner and cooler than gasoline and helps reduce oil imports.


After debuting at a Kansas gas station in 2012, E15 has spread rapidly and is now sold in over half the country. RFA estimates that nearly 97 percent of registered vehicles on the road today are legally approved by the U.S. Environmental Protection Agency to use E15, and many also carry the manufacturer’s endorsement to use E15.

Some Facts about E15

E15 Reduces the Emissions that Cause Air Pollution

Ethanol is an affordable and effective tool for reducing emissions from the transportation sector that are harmful to our health. Because ethanol is a pure compound that is 35 percent oxygen, it burns more cleanly and completely than gasoline, which can contain as many as 1,000 unique compounds. Reducing these emissions means fewer cases of respiratory illnesses, asthma, heart disease, lung disease, cancer, and even fewer premature deaths.

E15 Holds Down Prices at the Pump

Using ethanol in the U.S. fuel marketplace helps lower gasoline prices by expanding gasoline supplies and reducing the need for importing expensive, high-octane, petroleum-based gasoline components or more crude oil from unstable parts of the world like the Middle East.

E15 Helps Fight Climate Change by Lowering Carbon Emissions

Ethanol helps reduce greenhouse gas emissions by 40-50% compared to petroleum. By displacing hydrocarbon substances like aromatics in gasoline, ethanol significantly reduces emissions of air toxics, particulate matter, carbon monoxide, nitrous oxides, and exhaust hydrocarbons.  You can read more about ethanol’s impact on the environment here.

E15 Lowers America’s Need to Import Foreign Oil

Increased ethanol production continues to help diversify our nation’s fuel pool and dampen the impacts of petroleum market shocks. You can read more about how ethanol helps reduce our dependence on foreign oil here.



E15 is Safe and Economical

E15 has proven itself as a safe, economical and popular alternative to gasoline. It is estimated that American drivers have logged over a billion miles on the fuel, taking advantage of its affordable price and its environmental benefits. See which vehicles are approved for E15 use.


E15 is not recommended for motorcycles and vehicles made before 2001, light-duty trucks, and medium-duty passenger vehicles.  Off-road vehicles, such as boats and snowmobiles, all off-road equipment, including lawnmowers and chainsaws, and vehicles with heavy-duty engines should use other alternatives as well.  For more information, please see the RFA Automobile Fact Sheet for E15  and the RFA FAQ Sheet for E15  that address fuel economy, the testing of E15, and other frequently asked questions.
