Thanks for the question, Terry!

You do not have to fill up the tank after adding Sea Foam. That plan will work great in your motorhome. Just make sure to add at least 1 oz of Sea Foam per gallon of fuel in the tank. A second can wouldn’t hurt if you want to get some extra cleaning power in addition to stabilizing the fuel and protecting the fuel system.

Thanks for the question! Adding Sea Foam to your mower’s tank will help prevent the fuel from breaking down and help prevent varnish from forming in the fuel tank. Varnish is a very common cause of poor engine performance in small engines like mowers, so Sea Foam in the gas tank during storage is an easy way to prevent issues.

You’ll want to add at least 1 oz of Sea Foam per gallon of fuel in the tank. However, it’s okay to add more than that. In fact, a higher concentration will do a great job cleaning any varnish in the fuel system.

Here’s what I’d do: add about ¼ of a can (it doesn’t have to be precise). Then, run the engine long enough for the treatment to work through the entire fuel system (about 5-10 minutes of idling).

Thanks for the question, Brian. Yes, you can add Sea Foam to 2-stroke fuel mix to winterize it. Make sure you add at least 1 ounce of Sea Foam per gallon of fuel. It doesn’t hurt to add more than that, and it’s better to add a little more than not enough (for cleaning up a 2-stroke that’s having trouble, we recommend adding a 1:2 ratio of Sea Foam to fuel). Before you store it, run the engine for a few minutes to draw the treated fuel through the entire fuel system.

Thanks for the question, Steve!

Sea Foam in your fuel can actually help recover lost fuel efficiency, or keep your Goldwing running as efficiently as possible.

Sea Foam Motor Treatment is safe to use in every tank of fuel. It doesn’t have any harsh chemicals, and it’s made with 100% safe petroleum cleaning and lubricating ingredients that can’t harm parts or components.

Adding Sea Foam to your fuel tank regularly will keep the fuel system and critical engine areas clean, which will help recover lost fuel efficiency or prevent it from dropping.

If you’re riding it regularly during the season, you could add Sea Foam to every other tank of fuel. If it sits for while, add Sea Foam to every tank of fuel to prevent the fuel from degrading and forming varnish and deposits. If you store it for the winter, be sure to add some Sea Foam to the fuel tank before your last ride of the season.

Let me know if you have any other questions – happy to help!

Best,

Good question, Joe. Yes, you can use Sea Foam in gas that already has Sta-Bil in it. It’s safe to mix.
