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.
Oct 1, 2020 · Time to go 100 per cent propeller-head: Octane rating is an index of the knock resistance of a particular fuel compared to a laboratory standard kind of fuel called iso-octane. Which is actually 2,2,4 tri-methyl pentane - for those of you who remained awake for carbon chemistry in high school.
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.
The octane number of gasoline is one of the most important measures of gasoline quality to predict accurately the octane ratings of blending gasolines. This measured on a scale that ranges from that equivalent to isooctane (octane number of 100) to.
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.*
Octane Calculator. 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. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock).
