• E85 describes a blend of automotive fuel consisting of 85 percent ethanol and 15 percent gasoline. Vehicles able to run on this fuel generally pay less per gallon for E85 than regular gasoline, while burning far fewer emissions. Using E85 fuel also results in decreased fuel efficiency. Cars that run on E85 can also operate with regular gasoline, but not too many models have this dual, or flex-fuel, capability. The following list, by manufacturer, are some of the flex-fuel vehicles available.
  
  

Ford Motor Company

• Since the 1990s, Ford has offered flex-fuel vehicles. Some of the models sold with this feature include the F-150, Taurus, Escape, Expedition, E-Series vans, Fusion and Crown Victoria. Mercury brand models include the Mariner and the Milan, while Lincoln brand models include the Town Car and Navigator.
