Do a search on it. I beat this topic to death about a month ago.

Do a search for octane booster

 

You never said what you have for a power plant

Visit your local small airport .
Get some 110 ,AVgas in a jerry can & get some power

 

I have the same power plant you do, but Im assuming youre talking to green terror?

Green terror hes right, beofre rehashing this topic, what motor are you seeking the aforementioned octane boost for?

And to answer your question bluntly, they are a scam (the ones in a bottle from the auto parts store). Go buy some avgas like dennis mentioned or make your own.

And by the way, welcome to FTE
