I recently asked a question of a poster on youtube.com what would work to clean the inside of my truck engine and he recommended Seafoam Engine Treatment.

I've never heard of it, so if you've used it, let me know what results you got and how you used it.

Maybe others will learn something from this thread too!

Yes; in my fuel tank in my boat, to keep the carbon buildup in my 2-stroke motor always clean.

I've not used it in 4-stroke motors, but the action of the solvents would be to remove deposits and keep the fuel system clean.

I use in for small engines and vehicles as a gasoline additive. Seems to work.

I used it a few times right before my annual motor vehicle inspections, so my ol’ Ford Ranger would pass the smog check.

It always passed the smog check, so I guess it worked. It was either that, or the fervent prayer.

Haven’t actually torn anything down and measured deposits though.

Has an excellent reputation among two-stroke outboard mechanics. Certainly has some strong solvents in it.

Works but dont forget to slap yourself and check the headlight fluid, make sure you windows have plenty of elbow grease, sparkplug batteries are charged, and the flux capaciter is fluxing.

SeaFoam 60 years and still going. Must work, or it is the biggest scam ever.

Excellent product. Don’t overuse it. It will eat seals and gaskets if overused. A lot of fuel cleaners marketed under different names are naptha or similar compounds. Most are pretty much the same chemicals.

I have a lot of small equipment like weed eaters, generators, wood splitters, ect. that sit alot and get gummed up with bad gas. Will Seafoam help clear the gunk out so they will start after sitting?

Yes, used it on a 2003 Nissan XTerra throwing a knock sensor and catalytic converter code. It would throw the codes shortly after clearing them with IBD2 app every time. After using a can, the codes just came after about 4 months. Not a long term solution.

You have to be careful not to dislodge a deposit that may end up causing more problems elsewhere (e.g. clogging up a pilot jet or other small passage). It is always better to remove the parts and clean manually, even using the product full strength on the metal parts along with air to blow out. Then use Seafoam normal strength in the fuel to keep it clean.

I sed it in my transmission. It didn’t help the transmission because it was worn out. It did, though, clean our the return lines of the gunk that kept the holes from leaking. I replaced the lines. I would say it is good stuff.

I heard that too! Sounds like a great product if someone trusted it to clean their gun with.

I think I’d try it on my lowest level firearm first though.

No wonder boaters like it. Those seals can be a PITA.

Instead of SeaFoam why didn’t they call it PolarBear?

I've used SeaFoam for many years to keep my 1990 Goldwing motorcycle running well. Mix with gas per directions about every third tank of gas. Purrs like a kitten.

It works very well without being as harsh as some products. I have used it in older motors like my ‘72 Honda 750. I use Berryman Chemtool for modern injected motors.

A general note of caution about cleaning engines. You can ruin an engine by cleaning it if a piece of gunk falls free and clogs an oil port, or enough pieces of gunk fall free that the screen in the oil pan area clogs.

I never had it happen to me but I have been cautioned by experienced mechanics not to clean varnish and gunk from the engines of high mileage vehicles because the gunk can actually help keep worn engine parts more or less in place.

If you are wanting to clean varnish and gunk from rockers, etc, you can add 1/2 pint of Seafoam to the oil (5 quarts), drive 100 miles and change the oil. Note the color of the oil on the dipstick when you first add the Seafoam and how much darker it is 100 miles later when you drain the oil.

From everything I've read, don't drive the vehicle more than 100 miles with 1/2 pint of Seafoam in 5 quarts of oil.

It’s that ethanol (thanks, EPA!) that’s getting you. Ethanol is hard on rubber pieces and absorbs water like there’s no tomorrow.

Here’s a couple other things to try:

1) Sta-Bil. Designed to protect against the bad effects of ethanol in small engines that store gas.
2) If you have access to aviation gas, use that in your small engines. (Airport nearby? Pilot friend?) Av gas has no ethanol. I have heard that marine gas has little or no ethanol but I have no direct experience with it. Av gas works GREAT in small engines.
3) Religiously dump out your gas after using your small engine tools, especially if you use them infrequently.

That makes sense. Maybe adding it to the oil and running it for a few minutes then shutting it down for a day or so would give it time to dissolve the chunks. Or starting and stopping over several days.

If an engine was neglected and old it would probably need a special time table to work without causing damage.

I use it in my old VW Bug to keep the carb clean. Works really well, especially after the last carb went bad from build-up. Just dump a whole can into the gas tank and she runs like a charm.

Never used “Seafom” but I use LUCAS additive to my diesel fuel and the LUCAS “Oil” additive when I do an oil change. You will see an increase in mileage when you use both LUCAS additives.

Well there you go! That ought to do the trick.

Before ethanol, you could get away with leaving gas in small engines for an off-season or two. Not anymore.

I used to use Seafoam as a fuel treatment when we were spending a lot of time below freezing, and it worked well.

I’ve never heard anything negative about it.

I've seen where a lot of products use methyl ethyl keytone (MEK), the main ingredient in lacquer thinner.

When I was a kid playing with model airplanes, I remember the MEK my brother brought home from work smelled like lacquer thinner, but it cleaned my brushes WAY quicker and dried my hands out much more.

My kid used this on an old truck and screwed it up. He sucked about a whole bottle into the engine via the vacuum hose. The engine ran for awhile then cut out, thankfully in front of a garage which he had to pay to drain it.

Stuff works good - just not the whole bottle at once....

Check out on www.Youtube.com, that's where I first encountered the product.

It does seem from some of the video's that it work's. Like what other poster's have said use sparingly.

Maybe adding it to the oil and running it for a few minutes then shutting it down for a day or so would give it time to dissolve the chunks. Or starting and stopping over several days.

I started using Seafoam when I began getting tapping noises that I suspected was due to one or more lash adjusters not being properly oiled due to varnish/particulate buildup/clog. I ran 1/2 pint of seafoam 100 miles and then changed the oil. The tapping noises stopped but after about 3K miles returned. I did another 1/2 pint of Seafoam, drove another 100 miles, changed the oil and the tapping went away. Along the way I switched to 100% synthetic oil (Valvoline MaxLife). I haven't had tapping noises for quite sometime and when I look through the oil fill hole, I can see that the metal inside is getting cleaner.

Some people say just pour a quart of transmission fluid in the crankcase, drive 10 miles, change the oil and you'll have a shiny new interior but I would strongly caution against the "quick clean" techniques due to the risk of ruining the engine should an oil port clog.

If an engine was neglected and old it would probably need a special time table to work without causing damage.

One of the first things you might notice is oil leaks forming due to the gunk and resin dissolving away that had formerly been helping old gaskets maintain seals.

I am not sure that would work.....it doesn't really stabilize the fuel that has been sitting in a gas tank (use products like Stabil to winterize those). It's a gum/carbon-dissolving product to clean up RUNNING or POORLY RUNNING motors by freeing up piston rings, cleaning combustion chambers, etc.

A spray can of Berryman would be the easy way to bring the Evinrude back to life. Just give the fuel system and the cylinder a good dousing before starting it. Buy a new plug too.

If it won’t start after that, its got to be the mag points.

I have used it on the Camry, Saturn, and Ranger. I have had very good results. It seems to help regarding cleaning the gas tank, gas line, and injectors. I had used a good (expensive) gumout product for the injectors and the car still had some problems running. After the seafoam the car ran better than it had in over 50K miles.
I have yet to use it a second time in any of my vehicles (trying to follow instructions.) :-)

Considering how good modern detergent gasolines are these days, I wouldn’t waist my money. It may well be helpful in preventing heavy (high Mw, and/or highly branched) deposits from the oil in pre-mixed gasoline in 2-stroke engines, but I think it’s likely to be a waist of money for 4-stroke engines.

In case you care about these things, it was Mobil (prior to the merger with Exxon) that invented the detergent used in modern gasolines.

Just to clarify my post #42. I regularly add 1/2 pint of Seafoam to the engine oil 100 miles prior to changing the oil. It's not an instant clean solution but I can see that the rockers, springs, camshaft, etc are steadily getting brighter.

As I mentioned in #42, I suspected a tapping noise that sounded like a valve tapping was due to an oil starved hydraulic lash adjuster (valve lifter). The orifices on the lash adjusters are quite small, I believe mine are something like 1 mm. It doesn't take much to clog such small opening. The Seafoam definitely did the trick. Now that the tapping noise is gone, the only reason I continue using Seafoam is because I assume that as long as I can see varnish on interior surfaces, there may still be some varnish in the lash adjuster orifices. So, I keep on with the gentle cleaning.

Used it for many years in work vehicles, Jeep I6’s, 351 Clevelands, older 350’s and other basic engines. Never used it in anything with lots of plastic or aluminum parts.

Watch lots of utube videos before you attempt it. You can do incredible damage if you do it wriong!

Oh yeah, don’t do it on a sunny Saturday morning when your local EPA spys are watching, the smoke cloud is unbelievable.
