Avgas is tricky like that. Don't pull up in your car and fill the tank. Luckily I have a place that sells 110 racing fuel close by. As one of the guys above said, you don't always hear the detonation. I lost an engine in my 04 Ram that way. So, if you need some sweet stuff put it in there! Don't risk engine failure.

You can do lots of research about boosters online. Lots of choices with the inhibiting factors being cost and availability. Anyone ever hear of the old school putting moth balls in your tank for an octane boost? Be sure and put it in cheesecloth or something or the fragment could stop up your sending unit. Racing fuel is your best bet and it smells soooo sweet!

cjskotni let us know if the stuff you bought makes the pinging go away. I know it's an unscientific test, but I'd be curious as to your opinion.
