E85 is a fuel blend containing up to 83% ethanol and 15% gasoline and contains about 98 octane. E85 can only be used in flex-fuel vehicles (FFVs). There are now more than 24 million FFVs on the road, or nearly 10% of all vehicles, representing more vehicles than require premium today. Click here for a list of all FFVs.
There are several ways to determine if a vehicle is an FFV:
- Sticker inside the vehicle’s fuel filler door; some manufacturers add yellow gas gaps for additional recognition.
- FFV badge on the rear of the vehicle.
- Check the owner’s manual; it’s also encoded in the vehicle’s identification number (VIN).
Retailer Equipment
E85 does require different equipment than regular gasoline. E85 can easily be incorporated into multi-product dispensers, eliminating the need for stand-alone equipment. View the Handbook for Handling, Storing & Dispensing E85.
Fuel equipment sold today is typically tested by the manufacture to prove that it is compatible at one of four levels of ethanol: 10% (E10), 25% (E25), 85% (E85), or 100% (E100). That marks the highest level of ethanol that equipment has been proven to accommodate without a risk of failure (i.e. spilling fuel into the environment). Some equipment, like most new underground storage tanks, already comes compatible at the E85 or E100 level.
Incentives
There is a federal alternative vehicle refueling property credit for fuel retailers to offer E85. This credit is available through tax year 2021. Click here for more information.
