The American Ethanol Brand

Bringing the confidence of 7 million miles of racing to a pump near you.

For the past four years, American Ethanol has been the fuel of choice for NASCAR in the form of E15. The American Ethanol brand is on the green flag at the start of every race and appears prominently on cars and promotional materials on the NASCAR circuit. Now the American Ethanol brand is making its way to the consumer marketplace through a nationwide pump labeling initiative—and Nebraska is one of the first states to implement it. The American Ethanol brand labels will help you more easily identify this clean-burning, homegrown fuel at the pump. As the labels are adopted nationwide, you’ll be able to find American Ethanol virtually anywhere you travel.

Look for these labels where you fill up:

A blend of 10% American Ethanol and 90% ordinary gasoline. Approved for use in all standard vehicles.

A blend of 15% American Ethanol and 85% ordinary gasoline.   Approved by EPA for use in all light-duty vehicles (cars, SUVs, vans and pickups) model year 2001 or newer as well as all flex fuel vehicles.

A blend of 30% American Ethanol and 70% ordinary gasoline. For use in flex fuel vehicles only.

A blend of up to 85% American Ethanol and 15% ordinary gasoline. For use in flex fuel vehicles only.


When you pull up to the pump, you may think you’re just filling your tank.  But you’re also filling the air with dangerous toxics that threaten your health.

It’s all about octane—and what is added to our fuel to get it.

At one time, oil companies added lead to gasoline to increase octane. Lead was eventually banned when it was linked to serious health concerns involving nerve damage, fetal development and high blood pressure.

Then MTBE was added to gasoline as an octane enhancer. That was also eventually banned due to its tendency to pollute groundwater.

Today, a deadly combination of toxic carcinogens known as BTX (benzene, toluene, xylene) is added to fuel to enhance octane.  And the health threats of these cancer-causing additives are growing with every research study.

These carcinogens do not completely combust in the engine. As a result, fine and ultrafine toxic particles leave the tailpipe and enter the air we breathe. These particles are linked to serious health problems including asthma, lung and brain cancer, and heart disease. These toxic particles are especially dangerous to infants, children, the elderly and people who suffer from cardiopulmonary or respiratory disease.

What is octane?

Octane is a measure of the ignition quality of gasoline. The higher the octane number the less susceptible the fuel is to “knocking.” Knocking occurs when the fuel prematurely burns in the engine’s combustion chamber due to compression, instead of being ignited by the spark as the engine is designed. The higher the octane number, the more compression the fuel can withstand before igniting.

American Ethanol is a non-toxic, clean burning source of octane. American Ethanol doesn’t release toxic particulate matter out of the tailpipe.

With American Ethanol, we can get the octane our engines need to perform—and we clean up the air at the same time.

American Ethanol adds oxygen to fuel—and that helps the fuel burn more completely.  It’s like fanning a dying fire. You add oxygen and the fire keeps burning. That’s what American Ethanol does in gasoline. That means more of the toxic compounds are completely burned in the engine rather than coming out the tailpipe.

Higher blends of ethanol such as E15, E30 and E85 dramatically reduce the levels of BTX in fuel. It’s simple math: The more American Ethanol in our fuel, the lower the levels of carcinogens in our gasoline—and in the air we breathe.

American Ethanol also reduces greenhouse gas emissions, which have been linked to climate change.

American Ethanol should be the preferred source of octane in our fuel if we’re serious about improving air quality and reducing the costly impacts of engine exhaust on human health.

Flex Fuel Vehicles


About one in seven Nebraskans is driving a flex fuel vehicle—and many don’t even realize it.

Here’s how to know if you’re driving a flex fuel vehicle.

  • Check your owner’s manual.
  • Look for a flex fuel badge on your vehicle, usually on the trunk lid, rear door or tailgate.
  • You might also have a yellow gas cap or have a decal inside your fuel door.

If you have a flex fuel vehicle, lucky you!

You have the ultimate in consumer choice at the pump.   You can fill up with any blend of American Ethanol and gasoline from E10 up to E85—in any amount at any time.

A computer in the engine automatically adjusts for the varying percentage of ethanol in the fuel.

With a flex fuel vehicle, you can take advantage of fluctuating fuel prices by choosing the American Ethanol blend that makes economic sense.


When you’re calculating the most economical flex fuel purchase, be sure to consider your cost per mile—not just miles per gallon!
