Should I use more than 2 oz of Sea Foam per gallon in my Polaris side by side? [SOLVED]

Thanks for the question, Robert. You’re on the right track – adding 2+ ounces is a great cleaning dose. Sea Foam is petroleum-based, so it’s safe to run at higher concentrations. In fact, a stronger concentration works better and faster if you’re trying to clean things up.

If you want to do a deeper clean once in a while, you can:

• Wait until you have a low tank of fuel
• Add 2+ ounces (I like to add an entire 16 oz can to 1-3 gallons of fuel)
• Use up as much of the treated fuel as possible before you refill the tank

That higher concentration helps liquefy and clear out any gum and varnish that may be starting to build up.

2 oz per gallon still works great as a preventative maintenance dose if you add it to every tank. Adding a higher concentration is good if you want an occasional strong cleaning dose.
