Generally if you want 100oct you should just buy 100oct. It is not good for your precious rubber seals to run toulene at over 30% of your gas.

Anyway heres how much you need to get to 100 oct:

94 * 4 = 376

(376 + (114)x) / (x+4) = 100

Solve for x = 1.71 gallons toulene which is 30% of the gas.

This is assuming 4 gallons of 94 is already in the tank
