This has been discussed but I'll post again, I talked to a petroleum chemist about the different octane's and he said the oil companies use toluene (117 octane) to raise 87 to 91, 93. For ten gal. he suggested a mix of 1.5 gal. toluene and 8.5 of 93 to get close to 100 octane. Adjust for your available gas.
NOTE: he said the ten gal. should not exceed 2 gal. toluene and 8 gal. of gas.
