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.
