I have used seafoam for several years in our MH when I know it well be sitting for a few months. It can't hurt. I also use it with non ethanol gas in all my small engines, mower, trimmer blower. My Stihl chainsaw only has to run every 2 to 3 years and sits with fuel in it all that time. It starts in 3 pulls every time. I am a firm believer.

Menards has it but you probably will find it cheaper on Amazon.
I dont recall ever seeing it on my local wallyworld shelves.
I also prefer marvels mystery oil, it's cheaper and works as well or better than seafoam.
But it is also something I grew up with. So there is some prejudice there heh.

I think the answer is "Yes".

What you will find is that most people recommend what they use and there is no real testing.

I have been using Seafoam for many years. I had a generator that would not start in an RV I picked up. I was on the road an a local servicing dealer was able to clean up the carb but said it likely needed a new one, but did not have it on hand. He recommend Seafoam thinking it might help clean things up more.

It worked so well I used it in all of my stuff and has worked very well. Again, no actual testing......

I would never think of MMO as a fuel stabilizer but I guess they do claim that as a benefit. Here's an excerpt from an online comparison...
https://carwrenching.com/marvel-myst...l-vs-sea-foam/

"Marvel Mystery Oil vs. Sea Foam: As Fuel Stabilizers

You wonít need to think about fuel stabilization if you drive your car daily. Thereís not a chance that the fuel in your daily commuter is going to go bad. The only time you need a fuel stabilizer is when you plan to store your vehicle or you donít drive it regularly.
Leaving fuel to sit in the tank over time causes many problems to the engine. But, you can add a fuel stabilizer to ensure it doesnít lead to trouble. As a fuel stabilizer, you will need one ounce of Sea Foam for each gallon of fuel in the tank. However, you only need four ounces of MMO for every ten gallons of fuel.
Both of these additives can work as a fuel stabilizer, but Sea Foam clearly does a better job. It provides superior results when it is put into fresh fuel, providing stabilization for a maximum of two years."

My V65 Magna has never had the carbs apart since 1983 thanks to Stabil. Other V65 owners have rebuilt their carbs many times. My snow sleds are the same way. I wouldn't even dare to try anything else. Good luck with the other stuff though.

I am in the Sta-Bil camp. 12+ years of use in every gallon of fuel that I buy that is destined for dirt bikes, ATV's, lawn equipment, ect and no equipment issues. And believe me, I've got plenty of humidity in Florida for the ethanal to absorb. Nothing against SeaFoam except cost, I can treat 320 gal of fuel with 32 Oz of Sta-Bil 360 Marine for about $20.

My MH gets 6 oz for its 55 gal tank at every fill up before parking when 30 days or more to my next trip is likely. That way when I exercise the onboard generator, it's carb is filled with treated fuel. No need for shutoff valves or worry about running it dry.

Good Luck, you results may vary.

I dont use it as a stabilizer, I never claimed I did.
I stated I use star tron and use MMO instead of seafoam.
I only use seafoam when it's free and I use it the same way as I use MMO. Upper engine lube/cleaner
I used stabil for years also with no problems.
I believe star tron is superior from my research and is why I switched.

Sorry for the wrong interpretation. I think we are in complete agreement. I bought a case of SeaFoam from Zoro as I have used it in everything and had a truck mechanic friend recently recommend it for diesels as well.

Comments please.Thanks
We have always used SeaFoam in our stored fuel, generators, gasoline powered tools, and all of our vehicles with excellent results.

I switched to Star Tron years ago, at the recommendation of a Mercury Marine engineer. I have used it in stabilizing ethanol gas for years in all of my gasoline applications. I have never had a problem with carburetors or fuel injectors since then.

Both are good for fuel stabilization, but Sta-Bil will effect the Octane level. I used stabil for years but have been using Sea-Foam for over 15 years with better results from its cleaning ability and stabilization. Just my experience.

I put Seafoam in my boat and I have had it sit two years and the fuel was fine. I do not fill the boat up and just add fuel when ready to use the next year or two. Seafoam is $7.49 on Amazon which is cheaper than any auto parts store I have seen. Good Luck..

I would highly recommend a product called Pri-g. it was originally developed to keep fuel fresh on commercial sites. One ounce treats 16 gallons of fuel. Pri-g for gasoline and Pri-d for diesel. Check it out...
