Thanks for the question!

Yes, you can absolutely add Marine PRO to your boat’s fuel tank and mix it with Sea Foam Motor Treatment. Add enough Marine PRO to make sure there’s at least 1 oz of Marine PRO per gallon of new fuel. (1 oz per gallon is the recommended minimum for storage…it’s safe to add more, so don’t worry about being precise or about how much Sea Foam Motor Treatment is already in there).

Thanks for the question Vance! Yes, Sea Foam Motor Treatment added to the fuel will clean the combustion chamber on your Champion generator. It’s safe and effective in that model. You can use Sea Foam in any gas engine.

For cleaning, it works best to add a high concentration of Sea Foam to the fuel. Adding 8oz to 1-2 gallons of fuel works great for this.

Hope that helps and let me know if there’s anything else!

Best,

Hi James,

Thanks for the question! This question requires a little more attention to detail. Please call our Technical Department at 952-938-4811.

Thanks for the question, Paul!

No, unfortunately it won’t. It’s best to drain any old, degraded fuel from the tank.

If added to fresh fuel, Sea Foam will preserve its volatility and prevent it from degrading.

If you do have old fuel, it will reliquefy any varnish or residue that has formed. If you’ve got a vehicle or engine with old gasoline in it and you can’t drain all of it, add some Sea Foam and fresh fuel. A full 16oz can added to a gallon of fresh fuel is a good start. Run that through the engine and it will clean the entire fuel system.

Hope that helps and let us know if there’s anything else!

Thanks for the question, Bruce!

No, an open can of Sea Foam won’t go bad. A sealed can of Sea Foam Motor Treatment will last several decades. An open can that has the cap on tight will last a few years.
