Seafoam for real?

[swreeder]

I have had great luck with it reviving several small engines over the years for myself, friends and family. Always have a few cans on hand.

ProjectFarm has done a ton of videos and actual tests on it, pretty informative.

I add stab and seafoam to all my gas at home, small engines get some in the oil the last time I run it before an service if I remember. Maybe it’s snake oil, maybe not, doesn’t seem to hurt.

I remember before the days of ethanol a carb rebuild and cleaning were few and far between. Then ethanol came along and I became a amateur carb rebuilder. Sea foam works, don't care how but it does. had an enrichment jet constantly sticking on a two stroke, rebuilt and cleaned the carb 2x it stuck again was ready to burn the darn thing, calmed down and added sea foam never had a problem since.

I’m one those skeptics when it come to additives. I’m not a fan of adding stuff to my fuels or oils unless it’s for a specific reason. For example I use Stabil in my gas that will sit around for more than a few weeks and I add anti gel additive to my diesel in the winter.

Seafoam seems to be one of those miracle additives that I think works. Mainly in small engines that are running a little rough. If this actually does something, how does it work? I assume some kind of cleaner?

If you want a testimonial from a rando on Teh InterWebz...

I got rid of my boat about 8 years ago, but if you’ll search my username (same as here) on the iBoats forum I should pop up somewhere.
I still drop SeaFoam in the gas tanks of my F150 and my wife‘s Subar Forester ever 2-3 months.

It works well as a penetrating oil, too.

if you ever used Motor Medic#2 to to an intake cleaning (and pissed off all the neighbors with the smoke) you can do the same thing with Sea Foam.

follow the directions, it works.

Interesting video, a little to much fluff and drama for my taste but some decent testing.

Add a cap full of seafoam to your engine oil
and see what happens!!!

Fortnine is SOOO GOOD on all the bike related stuff. ;-)

An aside, When I put the bikes away for the winter, A healthy dose of two stroke mix goes in every tank

That is likely 120: 1 gas oil ratio. But it seems to have worked well for me for over 60 years of motorbike ownership ;-)

The weed whackers always need a bit of "fiddling" with the fuel screw to break up the clogs each summer.

Winter diesel fuel gets treated... A gel is just to big a hassel not to.

I have used Stanadyne diesel additive for years in my Dodge truck, my New Holland tractor and my Homelite generator. Started using in the generator for pump lubrication purposes when they took most of the sulfur out of the fuel. When I first put it in my truck, I noticed right away that the Cummins was quieter. They all sit in a well ventilated pole barn, and I have never had any jelling issues, and yes, it does get cold here in Northern Michigan.

If you follow, " Rev up your engines," Scotty Kilmer , he has nothing good to say about Seafoam. I disagree with him. Which is okay, ..I still watch his channel.

The testimonials are endless and to some extent the number of users amounts to a positive vote for Seafoam. I have only seen ONE absolute certain example far beyond "I think it is smoother." We have a 1954 Massey Harris Pacer with a Continental 4 cyl engine and an updraft carb. The carb has been rebuilt with new gaskets and needle valves, etc. 3 or 4 times over the years. Since about 1965 it has frequently (like multiple times per hour) stumbled and chugged and stopped UNLESS I whacked the side of the cast iron bowl with a wrench (which I could barely reach by standing up from the driver's seat.) That jarred the float/valve loose, allowed gas into the bowl again and it would run for a while. About 5 years ago I gave it the first dose of any additive ever -- Seafoam. That float has never stuck again in the last 5 years and I have never again had to beat on the carb bowl again. I can barely imagine the grief it would have saved me had I known this would work over the last 50 years (if Seafoam existed then...)

Fuel stabilizer products are around 50% by volume detergents. I like having things that start and idle without annual teardowns. I use them in the stuff I don't use often and everything else by pouring a dose in my fuel cans before I fill them. Haven't had to clean a carb in years now.

 

[Cougsfan]

I am always skeptical about claims that say "I avoided problems by using a particular additive". How do they know that? Chances are very high they wouldn't have had a problem if they used nothing and cared for their vehicle in a reasonable manner. I view fuel and oil additives in the same light as I view vitamins and health supplements. The vast majority of them are over-hyped and not really needed.

 

[plowhog]

You all must be buying crappy gas, or I'm one lucky son of a gun. .... NEVER had a problem with starting 6 months or so later. Even storing gasoline for 6 months or so, and no issue using it.

You are saying gasoline stores better at 30 below zero?

I'm in this camp. Had reoccurring problems in chain saws, weedwhackers, augers and mowers until I started buying only no-ethanol high test gas and adding a 1cc dollop of StarTron to each 5 gal. can before filling it. Not a problem since.

A friend had an old pavement saw given him. We could not start the saw with the choke, so removed the plug, poured a little fuel into the cylinder and got it started. Did not run well and would not idle. I suggested he pour two capfuls of the sea foam into the tank. Started the saw as we had been and kept it running with the choke and throttle for about 5 minutes. Still didn't run or idle well. Put in the corner of the shop for several days before pulling it out and starting it with our usual method. The engine ran better and idled some. Back to the corner for probably a week before having time to play with it again. It started with nothing but the choke and ran reasonably well so we kept it running, blipping the throttle and flipping the choke on/off. The saw now starts, runs and idles well and I'm a believer

I have used Sea Foam, though I prefer Star Tron. I generally turn the gas off in my generator after every test run; but for some reason did not do that one time. Could NOT start it. A shot of starter fluid--no sermons needed, I know the risks--started it; but it only ran choked. I dosed up the tank with some fresh gas and Star-Tron and let it run for an hour. Shut it off and let it set. Without the choke, it started on the second pull. Never had a problem since. It seems that the magic juice cured my problem.

I don't use any additives and never have had annual teardowns and haven't cleaned a carb in decades, and I have a lot of seldom used engines (2 chainsaws, log splitter, riding mower, 2 push mowers, tiller, weed eater, fence post pounder, gas powered generator, high pressure sprayer, 3 motorcycles, along with 2 tractors, 1 truck, 2 cars, and I forget what else. The majority of those devices are well over 10 years old).

Am I just lucky?

I have to admit I do use non-ethanol gasoline in all my gasoline powered devices except my cars. Some of them set for a year or longer between uses, and if I know it will set for a while I will shut off gas (if it allows) and run the carb dry after use. Perhaps we use a different method of insurance to avoid the same problems.

when you blow a engine because you have a plug injectors (on a two stroke) or you have to clean a carb every spring and once you used a product you don't have too then you know ...
