In higher-compression engines, ethanol can eventually enhance the mileage. My mom has a Brazilian-made Chevrolet Celta (basically a rebodied Opel Corsa B) with the 1.0L VHC engine, which compression ratio is 13:1, and it knocks like hell when the ethanol content in the Brazilian gasoline is lower than 25%. Back here ethanol blends in gasoline are mandatory, around 20-25% depending on the sugarcane harvest, the regulator stocks at National Petroleum Agency and other factors. It's the cheapest octane booster back here...
