Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels

Green Car Congress

Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. There have been many studies that have investigated the potential change in CR enabled by a given increase in fuel octane rating while maintaining similar knock characteristics—these, Leone et al.
