Will Sea Foam or Marine PRO interfere with other another additive in my boat’s fuel tank? The question has to do with my 1999 40 hp Mercury outboard.

There should be no concern Henry. ┬áSea Foam or Marine PRO mixed in gasoline with another fuel additive should not have any adverse effect. ┬áSea Foam and Marine PRO are made from petroleum, very gentle, and won’t cause any reaction with other additives.
