E85 for our cars is basically cheap race fuel. High octane, and also ethanol has a cooling effect in the combustion cylinders. My car loves it.. I run 25-30%... have been for months. Too much more E85 than say 40% and you'll probably run into fueling issues that you wouldn't get with race fuel.. but 100 octane race gas is what... $8 a gallon?
