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.
Dec 8, 2020 · By blending pump premium (or 91 if you like) with E85, you can create a custom blend of high-octane fuel. Cost Savings Through Better Chemistry. Simply put, if you mix 5 gallons of 91 octane pump gas with 5 gallons of E85, you get 10 gallons of a 96-octane fuel that’s very close to E50, or 50-percent ethanol and 50-percent gasoline.
Aug 15, 2011 · A gasoline with an octane number of 92 has the same knock as a mixture of 92% isooctane and 8% heptane. 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.
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.
Use our easy mpg calculator to work out your fuel consumption. So is the answer to just use the highest RON fuel available? Not necessarily. If the RON of your petrol is high enough to completely suppress engine knock then moving to a higher RON fuel will not improve performance or fuel economy. RON is not a measure of how 'powerful' a fuel is.
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.*
