It does seem from some of the video's that it work's. Like what other poster's have said use sparingly.
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.
“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”
Muffler bearings need attention also.
Never used it myself, but a number of people on some auto sites I am a member of swear by it.
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.
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.
We use it quite a bit. Cleans carbs that have varnished up. Use according to directions.
Used it in a two stroke motorcycle that had been setting for ages. Got it started enough to get some SeaFoam laden gasoline through it and WALA! Cleaned up and ran like new. Really.
I’ve been using Seafoam for years, and it’s the only thing that will unplug the idle jets in my Kawasaki. I don’t know what I would do without it, other than pay for carb cleaning every few months.
“Must work, or it is the biggest scam ever. “
No, the biggest scam by far is fiat money combined with a tax on capital gains defined as increase in the number of dollars an asset like land undergoes when rampant inflation kicks in.
This is the grandest scheme of theft in all human history. Government gets to inflate the currency to pay its bills and later gets to take even more of your wealth by taxing an “increase” in the price of your home or farmland due solely to inflation that government alone caused.
I’ve used Seafoam for while in my 1989 Yamaha motorcycle. It is good stuff, unless your carb(s) are really plugged. Then the Berryman’s (or other) spray carb cleaner is the only way to go.
Another good source is a product called Startron. It is another very good jet cleaner/preventative item. Startron is hard to find! Only place I’ve seen it is at Walmart, with the boating supplies (not the automotive section).
Agreed.
He also needs blinker fluid...be certain to use the colored kind where appropriate.
I really don’t like that Halogen Headlamp fluid, though. The color is never quite right when the beam hits the deer.
Mostly used to cure sticking valve lifters in car/truck engines.
Seafoam helps my snow blower engine run better. It is 4 cycle Sears and it has a crap Chinese engine on it. When Tecumseh went under, Sears and some other big box stores turned to a Chinese co. to make small engines. The carbs on these darn engines are no good and run rough and never seem to reach max power. Seafoam helps but is no full cure. I would have returned it, but the problem seems to get your attention just after the 1 yr. warranty expires. Replacement carbs are no better.
Lucas oil and gas treatments have worked well for me for years. My gas mileage went from 28 down to 19 over time and after using Lucas fuel treatment each fill up, my mileage rose each time till it was back to normal. I started using their oil treatment also. Currently, I am at 312k miles and purring along just fine. I see no reason to try anything else, YMMV.
Y yes, bought a 67 vw beetle which had been sitting up for about 10 years, Sea Foam in first tank and the roughness in the engine which was keeping it from reaching speeds above 50 mph vanished in 5 miles and smooth sailing since.
