Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. Higher octane fuel improves the efficiency of today’s engines through reduced spark retard (from optimum) at high loads, and could enable even higher efficiency if engines were optimized for higher-octane fuel.
