Agree. I can't find it now but a recent technical study of various ethanol blends showed that all cars have sweet spot ethanol blend where mileage is at its maximum - higher than either pure gas or E85. Some crs showed significant improvement at their sweet spot, others only a small amount. They tested several cars, including some that were not flex fuel. Sorry I don;t remmeber details but sweet spots were generally between E25 and E40. Maybe someone can find it with google.
