E85 is an alcohol fuel mixture that typically contains a mixture of up to 85% denatured fuel ethanol and gasoline or other hydrocarbon by volume. On an undenatured basis, the ethanol component ranges from 70% to 83%. E85 is found mainly in the Midwest where corn is a major crop and is the primary source material for ethanol fuel production; however as yet, there are still only about 800 filling stations selling E85 to the public in the US.
Ethanol is a biodegradable fuel additive produced from corn. E85 is an alternative fuel produced by blending 85% ethanol and 15% gasoline. It is a clean-burning, domestically produced, renewable fuel that contributes to decreased dependence on imported oil. Automobiles called flexible fuel vehicles are designed to run on E85.
E85 and Iowa State University Vehicles
Iowa State University Transportation Services is required by Executive Order 3 to use E85 fuel in all flex fuel vehicles. The university's vehicles can be identified as an E85 vehicle by one or more of the following:
- A yellow sticker on the WEX fuel card
- A yellow fuel cap or ring on the vehicle
- A E85 fueling message on the dash of the vehicle
For further E85 information please check out the following sites or contact Transportation Services. Transportation Services does have a list of E85 fueling stations inside the flex fuel vehicles to further assist our customers.
