A motor fuel is said to have an octane number of 20 when it is as good as a mixture of 20% n-heptane and 80% of iso-octane.
The octane number of gasoline is defined as the percentage of n-heptane present in a mixture of iso-octane and n-heptane, when the mixture has the same knocking in the engine, as the gasoline under examination.
The hydrocarbon iso-octane which has good resistance to knocking even in highest compression motors is arbitrarily given an octane number of 0. Whereas n-heptane which knocks the maximum is arbitrarily given the value of 100.
