Octane Boosters

I used to use a product called "Instead-O-Lead Gold". They had the regular lead substitute in a red bottle & the lead substitute with octane booster (the "Gold" version) in a black bottle. Don't know what was in the stuff but I added the reccommended amount to the gas in my 77 Harley & it eliminated all pinging & the bike ran great. Worked way better than toluene. Used to carry it with me whenever I went on a road trip. Wish I could find it now. Anybody finds some anywhere, buy me about 50 cases. I'll pay you back.
