It's probably similar to the 91 to 100 octane chart. All they do is average out the number ratio. Unfortunately xylene and toluene have gone way up, they used to be 35-40 for a 5 gallon drum, but not anymore. The mixture I made is with 4 gallons of 100 and 1 gallon of xylene. Cost for me is $43.00 and the mixture adds up to 103.4xx octane. VP racing MS 109 is 103 octane but they charge $64.00 for a 5 gallon drum. If you look at the main ingredients you'll see ......... you guessed it Xylene


I'd love to use leaded gas like C16 but cats and o2 sensors are way too expensive on these cars.
