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.
May 24, 2012 · Testing is the only real way to figure out how much octane your engine requires for sure. Start with a known higher octane than you think you need and read sparkplugs. Change to lower octane, hopefully less costly, and use whatever fuel doesn’t show detonation evidence, pepper spots.
First you need to calculate the percentage of each fuel that will be in the final mixture. Then, use this equation to find your octane: ( [ % Fuel A ] x [ Octane of Fuel A ] ) + ( [ % Fuel B ] x [ Octane of Fuel B ] ) = Octane of Mixture. Here’s an example.
Aug 15, 2011 · To use our calculator, simply enter the Research Octane Number and the Motor Octane Number; click on Calculate and the minimum octane number, what you see at the pump, is returned. We have inserted potential defaults that are correct for the most popular octane rating of 87.
Octane Calculator. When your engine builder recommends a different octane than is available, sometimes it is necessary to mix two different fuels to obtain the correct octane. How do you know how much of each to use? Try our octane calculator to reach your desired octane.*
