Xylene, octane booster
Thats what I did, just added to the tank and drove around for a bit to mix it up. Its WAY cheaper if you buy xylene in a 55 gallon drum from your local chemical supply store...I remember it being around 150 or so

its been so long since ive needed it i dont remember how i used to mix it.. but it may help you and could be worth looking into. but where i live im in the armpit of the USA.. we do a shatpile of oil refining around here so high octane gas is plentiful
