Any of you have any experience using fuel system cleaners in your Mustang GTs? If so, how often and what kind? I know that with cars I have had in the past, STP was not always the best, although it is the most widely available. I have not noticed any loss of power, etc. I am thinking about preventative maintenance.

Within the last 20K Miles I used 3 Bottles of "STP complete fuel system cleaner".
I am probabely not going to use it any more because i can't see/feel any difference.
Waste of money? -> I don't know.

Berryman's B12, Sea Foam, or Marvel Mystery Oil. You can find them at any parts store and are the only three that I would use in my car. I sell these products everyday so I know them pretty well.
