Short Answer - NO

Octane is widely misinterpreted as a measure of energy in the fuel. In reality it is a measure of resistance to preignition so a high octane fuel does not ignite as readily as a low octane fuel and often actually has less energy per gallon. Why is high octane fuel considered "high performance"? Because it lets an engine operate with higher compression and more ignition advance, which increases power but will result in higher gas consumption.

Pure ethanol supposedly has an equivalent octane rating of over 120.
