Seafoam has methanol in it and it doesn't go in my boat. Just stick with the blue Stabil. I especially wouldn't winterize with Seafoam.
From the SeaFoam site
Are you sure about the methanol part?Quote:
SEA FOAM Motor Treatment is a 100% pure petroleum product that safely and effectively cleans internal fuel and oil system components, helping your gasoline or diesel engine run cleaner and more efficiently. SEA FOAM is an EPA-registered product, and will not harm engine components, seals, gaskets, catalytic converters or oxygen sensors.
And yes, its ok to use with STA-BIL
i read the entire label on can in my hand no mention of the big M.
can't go wrong with sea foam
Done it for years!
I have used both for several years and never had anything but good happen. As far as avoiding SeaFoam due to Methanol. That's funny to me!!
when i winterize boats,i have my run tank mixed with seafoam,stabil,fogging oil and 2 stroke oil.works good;)
I'm not a mechanic nor chemical/petroleum engineer, so I looked to the "Seafoam" website: Motor Treatment - Sea Foam, for more information. Here is their claim: "SEA FOAM Motor Treatment is a 100% pure petroleum product that safely and effectively cleans internal fuel and oil system components, helping your gasoline or diesel engine run cleaner and more efficiently." I use it exclusive of other additives, including Marine Stabil, and I like the results.
The SeaFoam website lists the ingredients of SeaFoam as pale oil, naptha, and ISA. If you look toward the bottom of appropriate link, it shows that ISA is isopropanol. The Columbia Dictionary defines isopropanol as a colorless liquid that is miscible with water. It goes on to say that it is one of the cheapest alcohols and is a major component of rubbing alcohol. It gives synonyms as isopropyl alcohol and 2-propanol. I'm not a chemist, but it is definitely alcohol and, if my memory about rubbing alcohol is correct, methanol to boot.
I know SeaFoam is a great product to clean engines out and to use if you're running your motor regularly, but I wouldn't want to use it for winter storage or even if I was going to have an extended period when I wasn't using my motor and sure wouldn't want it in gas which has ethanol.
To each his own I s'pose. You'll hear 1 guy say "Stabil only", another says "never only Seafoam" and yet another says "all of it is crap, just shake a chicken foot over it every full moon and it'll never blow up". That's the trouble with outboards, so much voo-doo goes into it.
Personally, I put sea foam in every drop of gas I run in the O/B and will continue to do so until I hear a big kaboom while going down the lake. At which point, I'll buy another outboard and repeat the process.
Now as far as winterization goes, your best bet is to fog your cylinders, top off the tank with non ethanol fuel and treat that with whatever product you choose Stabil or SeaFoam or whatever.

I do what Wannabe does. It has worked ou fine for me.
Like Wannabe said.. To each his own.. But I have been using both since ethanol first showed up and I have never had any problems..
Careful you two, you're rurnin' my streak. Up till now, I hadn't been right in 2 years. Now I've got to start over.

I use seafoam and stabil together no problems. I have been using this combo for 3 years and never a problem.

Okay, I'm wrong about SeaFoam containing methanol...
I think I had read it does contain some type of alcohol, which was confirmed above. From my reading at Fueltesters, it says adding more alcohol to gasoline containing alcohol is not a good thing. That is why I came to the conclusion that I wouldn't use Seafoam anymore... About the same time Marine Stabil came on the market (the blue stuff) and I'm all over that with the blessing of Fueltesters.
I also installed an external fuel/water separator and filter on my gas line for extra protection. And run 89 or higher octane.
My Yamaha Ring Free additive is methanol. ugh
Unless pure gas prices fall below that of ethanol, our gas will always contain 10% ethanol by state law here in MO.
Where can you buy gas with no ethanol?:confused:Quote:

Got the best tip for winterizing the boat.
Don't do it!! Just keep going to the lake and fish. That way the engine runs in the winter:)
I am lucky to have 4 stations within 5 miles that sell non eth gas. I don't know how long that will last. It has been that way for 4 years.
