I'm a Seafoam addict as well.... beats using tools and carb cleaner to eradicate gum and gunk inside the carbs left over from Obama ethanol.
I tend to put it in and run the bejesus out of the engine to blow everything out the exhaust.
I use the stuff on the cars too.
For season storage, I would put $10,000 on black at Foxwood (Stabil) vs Red for seafoam...
Sorry, seafoam is not even close.
