An octane rating, or octane number, is ... (10% ethanol blend) 97 87–88 ... E10 which is an ethanol blend of fuel at 10% ethanol is available the octane rating ...
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 ...
In the aftermath of Hurricane Katrina in 2005, the price of E85 rose to nearly on par with the cost of 87 octane gasoline in many states in the United States, and was for a short time the only fuel available when gasoline was sold out, but within four weeks of Katrina, the price of E85 had fallen once more to a 20% to 35% lower cost than 87 ...
Both alcohols have a high octane rating, with ethanol at 109 RON (Research Octane Number), 90 MON (Motor Octane Number), (which equates to 99.5 AKI) and methanol at 109 RON, 89 MON (which equates to 99 AKI). [2] Note that AKI refers to 'Anti-Knock Index' which averages the RON and MON ratings (RON+MON)/2, and is used on U.S. gas station pumps ...
However, since ethanol has a higher octane rating, the engine can be made more efficient by raising its compression ratio. [ 33 ] [ 34 ] For E10 (10% ethanol and 90% gasoline), the increase in fuel consumption in unmodified vehicles is small (up to 2.8%) when compared to conventional gasoline, [ 35 ] and even smaller (1–2%) when compared to ...

As more effort is put into maximizing an engine to take advantage of E85's higher octane rating, engines achieve greater power advantages. One car that has higher power on ethanol is the Koenigsegg CCXR, which on ethanol is the fifth-most powerful production car, with 20% more horsepower on E85 than on gasoline. According to the manufacturer ...
