Octane is the measure of fuel quality. Octane is the number that measures the ability of gasoline to prevent pre-ignition or knocking. Fuels with higher numbers are less likely to cause pre-ignition or engine knock.

Cetane is the measurement of diesel fuel ignition quality, and the performance rating of a diesel fuel. The higher the Cetane number the better your diesel engine will perform.
