Iowa State University offers three different types of fuel for its fleet, plus electric hookups for plug-in vehicles.  Diesel is only used in select vehicles requiring diesel fuel. Gasoline with 10% ethanol is for all non-diesel vehicles. E-85 is available to all flex fuel vehicles.  E-85 vehicles may also be fueled with unleaded gasoline but is not recommended when an E-85 fuel pump is available. Check the WEX card or contact our office if there are questions on the type of fuel to use.

Fueling at the Ames site keeps fuel cost down. We offer all fuel pumps for all of our vehicles and other state owned vehicles at our Haber Road location in Ames.

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 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.

Wright Express (WEX) credit card is offered by Iowa State Transportation Services in order to fuel a rental vehicle when you are not able to fuel at the Ames location. The Wright Express card is used for the purchase of fuel only.

Wright Express requires a drivers ID when using the card. This number can be found in the 'What To Do In Case" packet in the glove compartment of every vehicle rented from Transportation Services, or can be found on the Fueling Procedures page.


ISU Parking Division, Facilities Planning and Management, and Transportation Services worked collaboratively to bring the electric car to the Iowa State University fleet. Two Level 2 ChargePoint charging stations have been installed at the Transportation Services depot. They are capable of charging four cars at one time. The charging stations are open for the public to use during the day.

When choosing this type of vehicle in our online Agile Fleet Commander site, your request will automatically go into a “pending” status. Our staff will reach out to the driver to make sure they are comfortable with the electric vehicle and verify the trip length to ensure that the electric vehicle is a good fit prior to changing the status of the reservation to “approved.” The Bolts are parked on the NW side of the Transportation Services lot, plugged into the chargers.

Anyone is allowed to charge their electric vehicle at the new charging stations. They are managed by Iowa State’s Parking Division and will function similar to a parking meter on campus. The maximum allowable time a non-ISU vehicle can be in the charging station is 4 hours.  The cost is $1.50 per hour, similar to other parking stalls on campus.

To start the charging session, users will need to download the ChargePoint App from either Apple’s app store or Google Play or obtain a personal ChargePoint Card. Users can go to ChargePoint to register. Once the user is logged in, select the station, and follow the prompts in the app.

The university owned electric vehicles will utilize the chargers in the evening and overnight hours to allow daytime usage to the public.
