how many gallons of 100 octane

This is just math skills and the web calculator is great, but basically 1/4 tank race gas (100 or 101) to bring it up to 93 octane and 1/2 tank race gas (100 or 101) to bring it up to 95 octane, from a base of 91 octane.

Are you looking at the JB2R?

1 gallon of 91oct plus one gallon of 92oct= 91.5oct
1 galon of 91oct + 1 gallons of 100 oct = 95.5oct

Just sum them and do the average.

i think he wants more than just 2 gallons of gas though

LOL
