i never hold my breath with that stuff, but when i do run it, i dump it in with little gas in the tank. if i do it on a full tank, i dump a couple bottles in. ive read everything from it does not do anything, to it killing rubber in the pump. i assume the former.
stuff these days is moron-proof (no offense; just my line of thinking). if it could hurt the car somehow, it would not be sold.
i might add that some have had good luck with the fuel system cleaners that hook up to the schrader valve.
good luck.

I think the reason they say to put it in a full tank is so it runs through the engine for a longer amount of time. I have been using that stuff (fuel injection cleaner) forever and it does work to a point. Don't expect miracles but it does work.
I once had a carb on a motorcycle (my cbr 600) that would flood the cylinders with fuel when it sat for a week or longer. I ran a half bottle through it with very little gas in it and the problem went away so obviously the cleaner cleaned whatever crud was on the needle in the carb off. It does work.
