Octane Calculator


Sometimes it is necessary to mix two different fuels to obtain the correct octane to maximize the performance of your race engine.  How do you know how much of each to use?  Try our octane calculator to reach your desired octane.*

Desired Octane What octane do you need?
Lower Octane What is the lowest octane you are going to mix?
Higher Octane   What is the highest octane you are going to mix?
Desired Gallons   How many gallons of mixed fuel do you need?
 
   

Low Octane Gallons

Use this amount in your mixed fuel

High Octane Gallons

Use this amount in your mixed fuel

*Octane calculator is a mathematical extrapolation only, and is not meant to be for scientific calculations. 

As a general rule, follow this chart:
9:1  = 90
10:1 = 94
11:1 = 98
12:1 = 102
13:1 = 106
14:1 = 110
