_Notes:_ The research octane number represents the ability of gasoline to resist auto-ignition, or knocking, under city (as opposed to highway) driving conditions. The octane index is the average of research and motor octane numbers (motor octane being the ability of gasoline to resist auto-ignition, or knocking, under highway driving conditions). An octane index of 87 in the United States is equivalent to about 91–92 RON.
