Consult the appropriate engine manual or vehicle owner's manual for the suggested minimum octane rating.

This method of calculation is good for all internal combustion engines, including automotive or general aviation. You may however, change the values appropriately. We have inserted potential defaults that are correct for the most popular octane rating of 87. To calculate simply enter the Research octane Number (RON) and the Motor octane Number (MON) click on Calculate and the minimum octane number, what you see at the pump, is returned. A gasoline with an octane number of 92 has the same knock as a mixture of 92% isooctane and 8% heptane. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock). Octane rating number is defined as a value used to indicate the resistance of a motor fuel to knock. This calculator determines the minimum octane rating, also know as the knock index, by the formula (R+M)/2.
