Yes
darkdan, I am pained by the excellent, although undeserved, reputation SeaFoam has. Your description sounds about right ... rather unremarkable ingredients that might have slight (but probably insignificant) benefits as a fuel additive ... but is NOT to be used in the crankcase as many do.
Regardless, the stuff is overpriced and should be passed up.
Johnny, far be it from me to question The Mullet, but I believe a good, pour-in cleaner used 1-2 times per year is an excellent practice. There's simply too much bad gas out there and I've seen the good cleaners like Red Line Oil SI-1 fix a stumbling engine with less than 1/2 of a bottle used.
