Ethanol, an alcohol fuel, provides high quality, high octane for exceptional engine performance and reduced emissions. Ethanol has been used in cars since Henry Ford designed his 1908 Model T to operate on alcohol. Trillions of miles have been driven on ethanol-blended fuel since 1980. In fact, several teams in national and international racing competitions, including Formula 1, Championship Drag Racing and NASCAR, use ethanol because of its high octane and exceptional performance.

What is E10?  E10 is a 10% ethanol-blended fuel.  Today all vehicles can run on E10, which is interchangeable with gasoline.  Since 2010, nearly all gasoline sold in the United States has contained 10% ethanol.


FACT: Ethanol boosts octane.

Octane is the single most important fuel property as higher octane is the key to higher torque, power and efficiency. With a 113 octane rating, ethanol is the highest rated performance fuel in the market and keeps today’s high-compression engines running smoothly.

FACT: Ethanol keeps fuel systems clean.

Ethanol and detergents help to keep gummy deposits out of a car’s fuel system. When ethanol and detergents replaced leaded-gasoline beginning in the mid-1980s, there were some initial problems with plugged fuel filters as deposits were flushed from the fuel system. Today, the use of unleaded gasoline has reduced deposits in the fuel system, and all gasolines sold in the U.S. include detergents designed to keep fuel systems clean.

FACT: Ethanol helps prevent wintertime problems.

Ethanol acts as a gas line antifreeze, helping reduce wintertime issues.  If you live in a cold weather climate and use ethanol-blended fuel, you don’t need to buy over-the-counter additives such as de-icers to prevent water, which collects in your fuel system, from freezing in your gas-line. 

FACT: Ethanol helps reduce harmful emissions.

The use of E10 reduces emissions of all criteria pollutants including carbon monoxide, exhaust hydrocarbons and fine particulates.

FACT: Ethanol reduces knock.

Ethanol has a significantly higher heat of vaporation, providing a cooling effect which helps reduce engine knock.

FACT: Ethanol does not affect driveability.

Tests and fleet studies, including those conducted by Amoco and the CRC indicated no difference in vehicle performance compared to gasoline without ethanol.

FACT: All auto manufacturers warrant their late-model vehicles for the use of E10.  Some even recommend it! 

“Of the 175,000 cars and small trucks that we have serviced in 42 years, not one engine has been damaged by ethanol. When it comes to the fuel line and primer, ethanol is no worse than gasoline when proper storage guidelines are followed” says Bobby Likis, car-talk host of ‘Bobby Likis Car Clinic’ and owner and operator of an award-winning automotive service facility.

Not all auto technicians and mechanics receive updated, factual information on the numerous changes that have been made in modern gasoline formulations. The need for timely, accurate information prompted the Renewable Fuels Foundation to provide an educational grant for the preparation of the Changes in Gasoline Manual: The Auto Technician’s Gasoline Quality Guide. The Manual is designed to ensure that service technicians have the information they need to understand fuel quality issues, both for diagnostic reasons and for the ability to convey accurate information and recommendations to the consumer.

FACT: Many automakers make Flex-Fuel Vehicles (FFVs) that can run on any blend of ethanol from 0-85%!

Since 1998, many automakers have produced flex-fuel vehicles (FFVs) that can run on gasoline without ethanol, E85 (85% ethanol, 15% gasoline), or any combination of the two.  There are now more than 20 million FFVs on the road and they are produced by GM, Ford, Chrysler, Jeep, Mercedes and others.  These vehicles use modern technology to automatically adjust the vehicle to whatever blend is purchased.  You can identify these vehicles by checking your owner’s manual, checking the rear of your vehicle for a flex-fuel badge, visiting with your dealer, or checking the fuel filter door or gas cap for more information.  FFVs must be identified in one of these ways, but each automaker is different.
