I'm a real seafoam fanboy. I ran four straight tanks of gas with seafoam just before I was getting my cams welded on my Taurus SHO. The guy who was doing the job said he had never seen a top end that clean before, and he had done over 100 of these weld jobs

I got a fantastic deal an inboard boat that was running very poorly. Two cans of seafood later, the boat was running perfectly.

I use a can about every six fills on all my vehicles. These products really do work.
