dude, ethanol is the octane booster... Ethanol has a octane rating of about 120...
I just prefer to run non-ox in anything that required premium (no ethanol added 91)
Also increasing the octane doesn't increase the energy in fuel, it prevents it from detonating
The required octane for a car is based on the compression ratio of an engine, the CR essentially determines the efficiency of an engine so unless you change it, (with new pistons or adding some form of forced induction which effectively changes the CR of the engine as it builds boost), then there is no reason to increase the octane of your fuel. reversely, that's why higher octane race fuels or ethanol (E85) works so well on turbo vehicles, you can raise up your boost substantially while still preventing detonation<--Engine Killer
