Octane number is also known as Octane rating. It is a figure indicating the anti-knock properties of a fuel, based on a comparison with a mixture of isooctane and heptane.

Definition: Octane number is a value used to indicate the resistance of a motor fuel to knock. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock). Also Known As: Octane Rating Examples: A gasoline with an octane number of 92 has the same knock as a mixture of 92% isooctane and 8% heptane.
