The octane number of the fuel, then, is the percent of the iso-octane in the matching iso-octane normal-heptane mixture. The octane number of a fuel has nothing to do with its starting qualities, power, volatitlity or other major characterisitcs. If an engine operates satisfactory with a fuel of a certain octane number, its performance will not be improved by using fuel of a higher octane.

The octane rating of a fuel is determined by matching it against mixtures of normal heptane and iso-octane in a test engine under specified test conditions. The test continues until a mixture of these pure hydrocarbons is found which gives thee same degreee of knocking in the engine as the gasoline is being tested.
