Seafoam was intended for CARBON build up in automotive engines. In the early 90s carbon was one of the most common engine problems for EGR systems and intake manifolds. I have personally seen this product remove carbon clogged runners on intakes that were so clogged that a drill bit was the only thing that would break loose the carbon. We would remove the intakes and flip them upside down and fill the ports with seafoam and let them soak for 24hrs. The next day you could literally empty the intake out and blow out ports with compressed air and you were done. Spotless like someone polished the inside of the intake !! Love SEAFOAM.

I found the best way to separate water from fuel is to drain out the entire fuel system and put in fresh gas with a little bit of fuel line dryer. If you want to save the old fuel, then put it in freezing temperatures (like a freezer, or outside when it's cold enough) then wait for the water to freeze and pour out the gas into another container.

Bottom line folks...there are no short cuts when you see water in your fuel. 

Good job donyboy73.  I really liked how you cautioned people not to use too much of this stuff due to damaging seals, diaphragms etc.  It is very harsh but a good product as you said and I am not knocking it either. 

I always enjoy your vids.  My (new last year) Stihl FS 100 RS started the very first pull yesterday.  Big fan of donyboy down here in Texas.  Thanks for what all you do for us.

I have some Seafoam, but have not used it yet because I was worried about any damage it would do to my equipment. That was nice to see this video on how it works with water in the fuel tank.

Because new gas contains ethanol and ethanol attracts moisture, I use isopropyl alcohol. The MSDS safety sheets for dry gas and isopropyl alcohol are exactly the same and if you buy it (91%) at the drug store it's about 4x cheaper than dry gas. I use about 8 oz. every other fill up all year long.

I use one ounce of Seafoam and ounce of ethenol remover to 2 gallons of gas and add it to my lawn tractor or small engines 4 cycle engines and have no problems run smoother and has cleared up hesitation been doing this for years and no problems when I put them in storage over the winter also no start up problems .

Great demonstration. According to Sea Foam's web site, this is mostly a proprietary hydrocarbon with some isopropanol. Have a good weekend!

Seafoam is a solvent meant to dilute the build up of carbon, ,    It works well for that application, ,   It is in no way a fuel stabilizer or blender, ,    In fact if you have a motor with heavy carbon build up, & you add seafoam as a fuel additive, it may make your engine run worse or not at all as  the carbon build up breaks down & gunks up the plugs etc..   It is a carbon de-solving compound.   Used for this purpose its kodi

alcohol additive works well with water contaminate. can get bigger containers of it at truck stops... often used in winter for the big rigs...

The gasoline we now use, has 10% ethanol, a type of alcohol, in it.
Since ethanol readily absorbs water, you should not have water in you gas tank, it would have mixed with the fuel.
Unless you put the water in the tank, or rain got into the filler, but that is unlikely.
In the 50's-80's, water was often used to remove carbon by squirting it into the intake, or using the PCV vale hose.
Water destroys carbon and oily deposits by effectively "steam cleaning" the combustion chamber, and softening the intake runners so the fuel normally can remove deposits.
Of course, you can cut down on deposits by changing the oil on schedule.
Too much carbon can also clog up Catalytic converters.

Gas line anti-freeze people. Specifically made to take water out of a fuel system. At the good old Canadian Crappy Tire you can pick up a bottle for around 3 to 5 bucks.

[DillysADV]

it would be interesting to do this test with with products like HEAT that advertise that they do clear up water issues.

What about if you experiment with water + gas then add seafoam, instead of only experiment with water + seafoam?

[BrucesShop]

Interesting Don. I use methyl hydrate to absorb water in gas. For small engines though I just discard it. (gas line antifreeze). Great video.

when I was a kid I remember there was a small can labeled napta in the house that my dad used to fill his lighter and my mom would use it as a solvent for laundry I remember getting ink on the sleeve of my shirt from Mom dab it with napta and it dissolved the ink. each time now I open a can of naphtha immediately the smell is just like that naptha when I was a kid I'm certain there's a large percent of NAFTA in seafoam to dissolve the Varnish in carburetors to open up the Jets to the size they were meant to be I'm certain it also cleans up anything in the fuel system as far as varnish and it probably helps with carbon too! being a solvent means it has a real small molecule, the same way paint stripper and brake fluid are small molecules so that they soak into molecules of paint or other substances there by loosening the paint dissolving it along with varnish and carbon ink so forth. the seafoam probably has a little isopropyl alcohol to help with dissolving some water in the gas.

Very informative video dony! I use small amounts of seafoam in my equipment & it works pretty well for me

[OpaKnows]

Thanks Dony, for your practical advise and the real world tes testing you do to let us see for ourselves.

[bigtechdude]

Nice video what about if the seafoam needs gasoline to activate it?

[vicstokes]

Problem...no calibrated (even roughly) measurements. With a marked jar, at least you could see if the "water " level had risen by blending with the isopropanol (alcohol) in the Seafoam. Since they are both clear liquids, how do you know if they blended at all? Put in a certain amount of water...mark level. Add Seafoam and agitate. Let settle....NOW check level of clear liquid. If it's risen then water and isopropanol have blended.

[motoman]

we use this stuff in the shop I have tried it with water in the tank and I had the same result. seafoam is an oil based product that is why it repels water. it does not do a very good job on varnish ither. what we have found it is a very good fuel stabilizer.
