Gasoline is primarily composed of octane. With that out of the way: the octane rating of gasoline only has a tangential relationship to the chemical octane. The octane rating is a measure of the resistance of gasoline and other fuels to detonation (engine knocking) in spark-ignition internal combustion engines.It is so named because a fuel composed of 100% iso-octane has an octane rating of 100.uels which are less resistant to detonation have an octane rating lower than 100, fuels that are more resistant to detonation have octane ratings greater than 100. Since ethanol is less explosive and more resistant to detonation than iso-octane, it has an octane rating greater than 100.
The phase-separated water/ethanol mixture would settle on the bottom of the tank near the fuel pick-up and would quickly stall out or even damage your engine. And because ethanol is used to boost octane, the remaining (low-octane) gasoline at the top of the tank would also have the potential to damage your engine. Note, however, that a fuel filter (10-micron) is essential to keep gunk from reaching your engine.
