It may be here for a long time. I hear South American countries have been using it for some 30 years and 90% of their vehicles run it.
It is true an engine needs much higher comp ratio to take full advantage of the E85 or E95 blends. As said the fuel to air mixture will be way different between gas and ethanol blend. The new FlexFuel vehicles can run both because the comp ratio is compromised and the computer senses when the fuel changes from gas to ethanol and makes mixture and timing changes to compensate for it on the fly. Ethanol is corrosive so changes have to be made to the fuel system also like to stainless steel.
In the last year there have been numerous magazine articles on the new fuels and great horsepower has been made with it. A little less mpg and price per gallon but more importantly it can help reduce our dependence on foreign oil and give our farmers another avenue to make a living.
