However, Gutierrez added that “…premium fuel provides no tangible benefits in fuel economy for most modern vehicles that run on regular unleaded gasoline.” Fuel Efficiency vs. Car Costs
High percentage ethanol mixtures are used in some racing engine applications as the very high octane rating of ethanol is compatible with very high compression ratios. Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low ...
