At ORNL, researchers are investigating the benefits of ethanol as a renewable octane provider. Use of higher octane fuels enables higher compression ratios, turbocharging, downsizing/downspeeding, all of which enable greater engine efficiencies. According to the findings, while neat ethanol may be trading at a significantly lower price than gasoline at any given time, retailers often peg E85 to E10 prices. However, a vehicle designed to run on 91-octane, as most vehicles are today, will not benefit from a higher octane fuel. There are no benefits to putting mid-range or premium octane fuel in a vehicle rated for regular octane. In such a case, you're in big trouble.

(6) It uses the fuel more efficiently (in other words, less power is lost to the actual ignition and to excess heat). As the octane number increases the compression ratio it can withstand before ignition increases too. Conversely, E85 (85 percent ethanol, 15 percent gasoline) makes up less than one percent of total ethanol consumption. Are there any disadvantages of using high octane gas in small - Quora Low-detergent gas might therefore result in increased emissions and decreased fuel efficiency.
