E85 is the term for fuel that is blended up to 85% ethanol and 15% unleaded gasoline. E85 is considered an alternative fuel under federal and state laws designed to increase our domestic energy security and reduce vehicle emissions. It looks and “Fuels” just like regular gasoline; however, ethanol does not contain many of the harmful carcinogens and other toxic chemicals found in gasoline.

Here are some quick facts about E85

• Environment- E85 burns cleaner, reducing ozone-forming pollution by more than 15%, carbon monoxide by 40%, greenhouse gas emissions by 25%, and over all air toxics by 40%. E85 contains 80% less of the toxics found in conventional gasoline.
• National Energy security – Do you know where your fuel comes from and where your fuel dollars go? The ethanol in E85 is renewable and “grown” here in the US . Research indicates a 67% net energy gain in corn-to-fuel ethanol processing and use.
• Performance – E85 has a 100-plus octane rating and its high alcohol content can provide 5% more horsepower in FFVs. Watch for an “E85 Boost!”
• Efficiency & Cost – FFVs are designed to also run on gasoline or any mixture of ethanol up to 85%. E85 has lower energy density than gasoline – Therefore, depending on the model, driving habits and conditions, you may experience a 10 to 20% fuel economy reduction. However, please note E85’s benefits and prices typically compensate for this loss in fuel economy for drivers.
• Maintenance – All FFVs carry the same warranty as gasoline-only models. Maintenance costs are roughly the same for FFVs. An FFV runs cleaner, possibly lowering your maintenance costs over the life of the vehicle.

• What is a flexible fuel vehicle (FFV)? FFVs are specially designed to run on and maximize any mixture of ethanol and gasoline up to 85% ethanol. Special on-board diagnostics “read” the fuel blend, enabling drivers to fuel with E85 or regular unleaded if E85 is not available. You can fill up with E85 every time at the pump to maximize the environmental and economic benefits of E85 or if its not available you can use regular unleaded or any combination of the two. You fill up the same as you always have. There are no switches or modifications to make due to the flexible fuel vehicle technology.
• FFV engines now come as standard equipment on many new models.
• Ford Motor Company, General Motors, Daimler Chrysler Corporation, Isuzu, Mazda, Mercede-Benz, and Nissan all offer FFV engines as standard equipment in select model vehicles-while little to no additional charge is incurred to the consumer. The vehicles are proven reliable and come with the same factory warranties as gasoline vehicles.
• Alcohol fuels are more corrosive than gasoline; therefore, fuel systems in FFVs have been upgraded to be alcohol compatible.
• Normally these parts include a stainless steel fuel tank and Teflon lined fuel hoses.
• The Primary Differences in an FFV is the fuel sensor that detects the ethanol/gasoline ratio. A number of other parts on the FFV's fuel delivery system are modified to be ethanol compatible. In addition to changes to the tank and fuel hoses, the fuel injectors, computer system and anti-siphon device have to be modified slightly.
• Can I convert my car to run on E85? There currently are no companies making conversion kits that are certified by the Environmental Protection Agency (EPA). Vehicles that run on multiply types of fuels have to be certified by the EPA for emissions on both fuel types. Emissions certification can be a very expensive process.
