What has been everyone's experience with these products?
Should I be worried about potentially damaging my engine?

I had to use the stuff this week because Sunoco was out of 94 AND 91 :blink:

Put in $10 of 89, threw two bottles of octane booster in case, and didnt boost at all till I could get to another Sunoco.

With that said, i couldnt tell you if it made a difference, no deto was heard, but like I said, I didnt hit boost at all. The car was idling funny, I thought it was a leak again, but after I filled up with 94, the idle went back to normal. Very weird.
