    Octane rating is a measure of a fuel's ability to resist 'knock. ' The octane requirement of an engine varies with compression ratio, geometrical and mechanical considerations, and operating conditions. The higher the octane number, the greater the fuel's resistance to knocking or pinging during combustion

    Reforming is a thermal or catalytic refining process in which the hydrocarbon molecules of petroleum are rearranged to improve its octane number; the resulting product is used in blending high-octane petrol.
