Ethanol FAQs


ethanol at the fuel pumpWhat is Ethanol?
Ethanol is a biofuel, but it is not the same as biodiesel. Ethanol is an alcohol-based alternative fuel that is made from a starch or sugar crop, but traditionally made from corn, grain sorghum, barley, potatoes and sugar cane. It is blended with gasoline to produce a fuel with a higher octane rating than unblended gasoline. While most gasoline is currently E10 (10% ethanol, 90% gasoline), E85 (85% ethanol, 15% gasoline) used in Flex Fuel Vehicles (FFVs) is another clean fuel option with superior performance characteristics.

  • Environmentally Safe – Less toxic than gasoline

While some CO2 is released during the combustion of ethanol fuel, it is recaptured as a nutrient in the crops used to make it. This is different than burning fossil fuel, which unlocks carbon stored deep in the earth for eons. Ethanol degrades quickly in water, so it poses less risk to the environment than petroleum.

By fueling their vehicles with ethanol, drivers can reduce our need for foreign oil and help clean up the environment.
