Seafoam is best for older marine 2-stroke inboards/outboards. I used to try it occasionally but didn't see much improvement in more modern no-lead/low lead 4-stroke engines. (short version) and an rarlier video of Seafoam vs Berryman B-12 and explained how B-12 was superior for todays engines, carbureted, injected and direct injection.
A lot of people still use Seafoam, but they are wasting their money.
