Does Seafoam work?

[TNhobbyfarmer]

If you have used it, do you think it works? What type engines have you used it in?

 

[MF283]

Works for me, use it in the tractor,mower, saws, weedeater , blower, UTV & vehicles.

I get the same results as Seafoam by keeping gas in a sealed container,,,
no air exchange, no need for Seafoam.
Keep gas tanks full,, the same effect as sealed storage.

I do not buy ethanol gas,,,

I just burn ethanol free gas. Problem solved!

Kerosene or diesel work just as well. For 2-cycle engines, just use a quality synthetic. I took apart a leaf blower that had been used heavily, for leaves, cleaning gutters, burning brush, sweeping sidewalks etc. for 5 years. The cylinder was bright and white glove clean, after using E0 gasoline and Red Line synthetic 2-cycle oil.

What he said.

For those of you in these threads that simply say "Use E0 gas" in some parts of the country that is easier said than done. I live in corn country with an ethanol plant in the same county I live in. Yea all our gas is E10. I am sure if they could get away with it they would make it E15. So other measures are needed.

In my experience - absolutely. I use it especially in small 2-cycle engines, but also in the carbureted Triumph with notoriously small pilot passages and orifices. It is a strong solvent for the sort of deposits that dried out gasoline makes, and can in some cases dissolve (minor) corrosion deposits caused by the water that becomes entrained in ethanol blend fuel. I use it at about 2x recommended dosage (in the tank) when I have a case where deposits are suspected, and at recommended dosage in the gas can for long term use in everything that gets filled with the can.

I try to use non-ethanol fuel in the cans, and when I do, it minimizes the need for SeaFoam.

And I don't always drink beer, but when I do, I prefer Leinenkugels.

It has worked the few times I used it. We have a 1997 Honda 300 4x4 atv we use for feeding horses and other farm chores. We use it every day, burn a tank of gas every 2 weeks. The carb and motor have never been apart. Gave me a little trouble, some rough idling and hesitation. Poured in a half bottle of sea foam, cleared up and has not re-occurred.

 

[jack707]

I used a can in my truck. I won't use 8 my chainsaw or spiller stability instead

 

[Garandman]

We had a 1997 Subaru Outback with 2.5L H4. It developed a part-throttle hesitation at around 145,000 miles. We put SeaFoam into the intake tract using a vacuum tube opening. It smoked out the neighborhood, but eliminated the hesitation.

We own a marina in Muskoka Ontario and have been using Seafoam for fifteen years with boats that we know are used very little (less than 15 gallons per season) by our clients. The boats are treated with Seafoam each fillup and have had no carb or injector issues; We believe to be better than fuel stabilizers in this application

 

[Tollster]

I run aviation fuel in all two strokes @ 50:1, anything that gets ethanol I turn fuel valve off and run carb dry. Motorcycles and quads.

I tried sea foam in my Wheelhorse, still sounds like it has dirt in the carb every now and then at idle.
Heard good stuff about it though, just didn't work for me.

I had a generator that was just running terrible from not much use. I dumped a little SeaFoam in it and surprising to me it cleared it up. I don't know what it did, but I'm happy.

 

[2LaneCruzer]

I like it. I use it frequently.

A friend of mine has a Champion 4000 watt generator with less than 20 hrs on it, that was stalling all the time. It would run for a couple of minutes, then shut down. It would re-start OK though, run awhile, then stall again.
I had a look at it, decided it was a fuel issue. I took off the float bowl and it had what looked like orange Jello in the bottom of the bowl. Cleaned that out and sprayed some aerosol Seafoam on the needle and seat and into the carb throttle body. I put a third of a can of Seafoam in the gas tank and started it up. Gave a few more shots of Seafoam into the carb as it was running, just enough to not stall the engine. Genny ran fine after that. Tested under load, no more stalling problem. Any carb cleaner would've likely worked in this situation, but I have had good luck with Seafoam.

This thread again? Seafoam was developed by a boat mechanic in MN who during WWII seen motor after motor with gummed up carbs. Its still a MN based co today. Do note, there was no alcohol in fuels at that time. He developed it to stop fuels from deteriorating when in contact with oxygen and doing that to a engines fuel system. Gasoline goes bad when in contact with oxygen and over time.

It works and I use it in all my seasonally used engines which may sit for a while. Draining the fuel doesn't work, since you can't get it all out, short of disassembling the system. I don't use it to clean systems out.
