Octane Rating Octane rating is a fuel’s ability to resist detonation and is classified by three main rating types. Octane rating is the measure of how resistant is gasoline and other fuels in the combustion engines to automatic ignition. It is the measure of a fuel’s burning characteristics. It is a standard measure of the performance of a motor or aviation fuel‚ the higher the octane number‚ the more compression the fuel can withstand before detonating. In broad terms‚ fuels with a higher octane
