From a midwesterner - above:

Ethanol (ethyl alcohol, grain alcohol EtOH) is a clear, colorless liquid made from starch crops, such as corn. E85 is a fuel mixture of 85 percent ethanol and 15 percent gasoline.

E85 is a renewable fuel that reduces air pollution and America's dependence on foreign oil.

Ethanol has no sulfur, which further supports its status as a clean-fuel option.

In the United States each year, more than 1.5 billion gallons of ethanol are added to gasoline to increase octane and improve emissions quality.

Ethanol production is extremely energy-efficient, with a positive energy balance of 125 percent, compared to 85 percent for gasoline. It's the most efficient method of producing liquid transportation fuels.

Ethanol is low in ozone reactivity, making it an effective tool in reducing ozone pollution.

Ethanol dilutes other potentially harmful components in gasoline such as benzene, toluene and xylene.

Still stupid?

Yep. Energy used to produce ethanol is excessive.
Corrodes fuel system parts. Horrid gas mileage!
