Stable is a good product and I use it for it's intended purpose which is eliminating moisture and stabilizing unused fuel in the gas tank. Stabil doesn't however raise the octane for those with higher compression engines that ping under load and do not want to retard timing drastically .

I used to take care of a large car collection. I rebuilt carburetors and blew out fuel lines for many years. Then Stabil came on the market and my boss says try it.

Bottom line Stabil only works for 12 months on the original tank of gas. After that you are pushing your luck and in my case I had to rebuild a whole lot more carbs and blow out a whole lot more fuel lines before I convinced the fellow that draining the gas was the easiest and cheapest solution to the problem.

Stor-N-Start is a marine grade gas stabilizer that is longer lasting.

Yeah, I would only be looking at Stabil marine for the moisture issue, nothing to do with octane.
I'm happy I currently have no pinging!
