Why You Should NEVER EVER USE SEAFOAM!!

In this video I show why you should never use Seafoam. I give three reasons right at the beginning. I also give reasons why you SHOULD use Seafoam. Hint: I use Seafoam and in my experience, the stuff works! Also, it's a pretty fun product to use with a super satisfying plume of white smoke after the 'hot soak.'

In this video you'll see me use Seafoam on my 1995 GMC Truck Suburban otherwise known as the GMT-400 or K1500. This truck is the same as the Silverado, Sierra, Tahoe, Yukon and even Escalade.

As a mechanic, I can honestly state that SeaFoam really does work! It is one of maybe four over-the-counter fluids that actually does what it says! I swear by it!

Seafoam just performed it's second miracle for me. $200 195, 000 mile '99 Accord. 'Check engine' light P0401 on for low flow in EGR system. Car was running fine. Engine warm, I removed the power brake booster hose from the booster. I poured about 6 ounces of Seafoam in a cup. I started the engine and used the brake booster hose and let it suck in the Seafoam. It was sucking too fast, so I regulated it a bit by partially obstructing the opening with my thumb and I did not fully submerge the end of the hose. Not revving the engine at all, just letting it barely idle and suck in the fluid. Small amounts of smoke started coming out of the exhaust, and even a little bit from between the exhaust manifold and pipe, and other places that don't normally leak. I continued adding the fluid. When the fluid was almost gone, I let the engine suck in enough to stall it. Not too much, I did not want to hydro-lock it.

I then let it sit for about 2 hours. I started it and made a big billowing cloud of very dense white smoke, which did in fact arouse the curiosity of at least one neighbor. I drove it hard and varied the engine speed and load for a couple of miles. On hard acceleration, it made even more thick clouds of smoke. I thought it was running fine before, but now the idle is smoother. I used an $18 ebay scan tool to turn off the 'check engine' light. A little bit of driving and a day later, and the light has not come back on.

Turning off a 'check engine' light for a few bucks is obviously a great deal, but for the other cars on the road keeping such a wide distance away from me, the nosy neighbor and of course the huge puffy clouds of smoke - might make Seafoam worth the eight bucks just for the entertainment value alone.

I use SeaFoam RELIGIOUSLY in all my small engines, state of the art 1953 Ford Jubilee Tractor and my GMC Envoy. It’s a great product and works as advertised. It’s great for stabilizing my fuels for next seasons use and I’ve never had a problem starting my mowers & such after being stowed for the winter. I’d recommend it highly.

[dannysteel]

I've been using Seafoam in all of vehicles for many year, including small engines like lawn mowers and tractors, and it really does work great.

You should never use Seafoam if you are in a Walmart parking at night unless you enjoy being interrogated/searched by your local Sheriff department for being suspicious(Williamson County

[jgizzy]

Legend has it he talks like this when the camera is off too.

[gmill]

You didn't kill the engine with the spray. I can hear your engine still running in the background while you're holding the empty can. You should lower your rpms and spray until it kills the engine when you feel the can is almost empty. That way you'll actually hot SOAK the engine. Once you shut off your engine most of the sea foam had probably already been burnt off. If you do it right, your neighbours should be looking out their windows and the fire department should arrive shortly after.

Oh I knew this had to be a bait and switch. Seafoam is the shiznit.

[justinreyman]

I would recommend doing this BEFORE you change your oil. Do the Seafoam thing, do your post-Seafoam drive, then do your oil change. At this point, you might want to also hit the MAF with some MAF cleaner, as part of this maintenance scenario. This is the sequence I would do, If I was going to use Seafoam to turn carbon into big billowing epic white clouds of smoke, while making my engine cleaner inside.

I tried seafoam on a ford 302 that was running rough, one thing I noticed is that the lifters quieted down, also the idle was much smoother, and it misfired a lot less and overall just sounded much smoother when driving. Your truck was already running good before you put the seafoam in, on an engine that runs rough, seafoam is definitely worth a try.

[x-man]

Your videos are fun Jimmy. Couple of points. The smoke you seem so interested in is really Seafoam that is not completely burned, so not getting a ton of "smoke" is not only OK, it is preferred by the method you are using (my guess is your neighbors agree with me also).
You have "throttle body injection", your injectors are in your throttle body so the distinction you were making was unnecessary.
And alternate way to do this is to find a manifold vacuum source, disconnect whatever it's going to at the manifold and rig a separate vacuum hose to it long enough to facilitate you dipping it in and out of a regular can (non-aerosol)of Seafoam.

I prefer this method and it does produce more "smoke" at momentary intervals. This way you can get more in at a time with each dip. You'll have to be on your game with the throttle if you are in a hurry the engine stalls, let it sit for a minute +/- and soak a bit. This way is a bit more nuanced and takes a little more time but IMO it's more effective. I can't prove it but logic says to me that the more product I can get in there at once, let it dwell and then repeat several times should remove more carbon and goo from your intake and combustion chambers. OK, fire away wise guys. LoL

Finally worked up the nerve to try it on my 3.5 ecoboost. It looked like it was on fire! Much smoother and quieter now. A touch better on fuel mileage also.

[JameyAston]

Your title got me. I'm so glad you have the same truck as I do. 95 Suburban. I"m right now following your video exactly!

[matthewdoenges]

Used seafoam on a 2012 outback, a 2008 civic and a 2000 Sierra. The outback and the civic had huge clouds of smoke that followed the car around for a while. People were trying to warn my wife in the outback that something was wrong. Best stuff I ever used.

[SystematicAce]

Spray directly into the main vacuum coming off the brake booster. I've got an 84 GMC k1500 and it works like a charm.

[PainterD]

Been using Seafoam for going on 20 years and I'll use it till I die. I just plain works for me. I especially like it for cleaning and storing my engines because it keeps the carbs clean for one, and it's a great fuel stabilizer for over the winter months when I don't use a few of my engines. I use on my motorcycles, lawn mowers, chainsaw, power ice auger, etc. to keep the running smooth and never have to do carb maintenance.

[krey]

If this is your third time treating the vehicle why would you expect to see a lot of smoke

[dennisgardiner]

Used Seafood on our 256K mile Ford Explorer. Used one can of Seafoam, which is hard to do, as the throttle is drive-by-wire. Got the engine to stall just before the can ran out. Let her heat soak 15 minutes. Started the engine back up, got some smoke. Put her in gear, gave it some gas, and she stalled right away. Got her started again an slowly, slowly drove off. The smoke show began. 250, 000 plus miles of carbon, and PCV residue in the intake came off. Hitting the expressway at 45 mph was a fog show. The truck now no longer shudders at part throttle, and idles super smooth.

[tcmtech]

I used it on my 99 Ford F250 Super Duty V10 and the Check-Engine light went off. It's never been off in the 12 years I have owned it. I think it broke something.

[Reallyu]

Your truck looks super clean on all the places I have seen on your videos. I think your engine was very well maintained by you. If you want try the high mileage version. Still I say 3 times same response. Your engine is clean. Celebrate that. Knowing that your engine has been clean all along. That is a great thing. So be happy. Doesn't make for dramatic video. Does make a statement of quality about you. ☝️😁
