An octane rating is simply a measure of how heat resistant a fuel is in order to prevent knocking. In other words, octane doesn’t enhance combustion — it prevents the air-fuel mixture inside an engine from igniting before it’s supposed to. The higher a fuel’s octane, the more resistant it is to knocking.
