This calculator helps you determine the octane rating of a blended fuel mixture from two different fuel sources. Fill in the volumes and octane ratings of both fuels and hit the “Calculate” button to get the resulting octane rating of the mixture.
We can model the heating values by using standard heats of combustion 1 for iso-octane and cetane. Engineers distinguish between higher heating value (HHV) 1 and lower heating value (LHV) 1 of a fuel.

Nov 17, 2022 · What is octane? In recent years, car manufacturers have been requiring or recommending premium gasoline (a high-octane grade of fuel) for use in more of their vehicle models. The difference in prices between premium and lower octane grades has also increased.
This calculator determines the minimum octane rating, also know as the knock index, by the formula (R+M)/2. Octane rating number is defined as a value used to indicate the resistance of a motor fuel to knock.
