How often should I use Sea Foam in a 2-stroke engine? [SOLVED]

Do you recommend using Sea Foam every time I put fuel in my 2-stroke outboard engine?

Thanks for the question, Frank. We recommend treating every tank unless you’re running the engine frequent enough to go through a tank of fuel every 2 or 3 weeks.  For example, our daily-driver cars and trucks get refilled regularly, so fuel is never in the tank long enough to degrade.  For most boat owners, we typically going to suggest treating every tank of fuel considering the engine might sit for weeks/months at a time without use. Hope this makes sense!
