End-Use Markets
Ethanol Use in the Market
To date, the U.S. has integrated ethanol into the market in two ways:
- Low-level blends (what is referred to as E10, which is a 10 percent blend of ethanol with gasoline)
- High-level ethanol blends (E85, which is 85 percent ethanol mixed with gasoline).
- High-level ethanol blends are primarily used in the Midwest, where much of the ethanol is produced.
Intermediate blends of ethanol (those that range between E10 and E85) still need to be investigated before they can be integrated into the marketplace.
Vehicles
Flexible-fuel vehicles (FFVs) can operate on any blend of ethanol with gasoline up to 85 percent (E85). About six million FFVs have been manufactured for the U.S. market, at a price competitive with conventional vehicles.
All vehicles manufactured since 1978 can run on E10. Current warranties for conventional vehicles would be voided if the cars were run on levels of ethanol higher than E10.
Information about converting vehicles to run on biofuels can be found at the Alternative Fuels Data Center.
Fuel Dispensing
Gasoline dispensers are not currently designed for storing and dispensing ethanol blends beyond E10. For high-levels of ethanol (E85) pumps designed and manufactured to dispense this fuel are available, but do not yet carry the Underwriters' Laboratories (UL) certification. Some Fire Marshals can grant certification in lieu of the UL certification (as in Minnesota).
