Instead of buying fuel additive, just pay the 20 cents more per gallon and get the higher octane gas. Yes, you do lose power when it retards the timing. And if you let detonation happens too often, it might damage your engine. Lets put it this way, you are only saving $3 or so if you fill it up 15 gallons when you buy regular instead of premium, is it worth it?
