The more I read and the more I think about it, I cannot see much need for seafoam over most of your other cleaners. I dont think it will hurt past cooking off mostly in your cats and making a not nice to breath smoke.
One place I would still use it... pouring a bit in your crankcase about 1/2 hour before your next oil change, and go for a drive around the block.
