seafoam ?

Anyone here used or has any experiences with "seafoam" ? Are the claims real or just another gimmick ?

Avoid it like the plague. YouTube nutjobs think the smoke coming out of the exhaust is carbon. The smoke is the burning seafoam they are sucking into their intake.

Easy to prove. Suck tap water into the same intake to get the same smoke out the tailpipe. Based on the idiots on you tube, the smoke caused by sucking tap water into your intake is proof that water cleans carbon as good as seafoam.

I'm amazed at how they don't see how obvious they caused the smoke filled exhaust via burning the additive NOT by burning off carbon buildup. That's like tossing gasoline on a fire then claiming the larger fire proves gasoline cleans wood. ROFLMBO!!!

Also, some have damaged their catalytic converter via seafoam.

Lol there is nothing wrong with seafoam. Its one of the most popular engine treatments out there. Worst case scenario it does nothing.

To reiterate:

There is NO need for "Engine Treatments" if you follow a proper maintainance schedule. Introducing that crap through your intake system is asking for trouble....

The fact that it may be "popular" means nothing more than that there are plenty of gullible suckers out there who fall for the marketing hype. It`s been happening since the invention of the automobile with products like STP, Slick 50, etc.

So you say avoid it like the plague just in case it doesnt do anything? Overreacting a little?

When add to the fuel tank seafoam will remove water and clean the entire fuel system.

When added to the oil it removes engine sludge.

What is so bad about that? And who says his car is properly maintained? Even the best treated cars need the injectors cleaned eventually.

How is "introducing that crap" asking for trouble? A think there might be a few million sucessful users of the product that would say otherwise.

When using it in the intake use the aerosol version if your afraid your going to hydrolock the engine.

I personally used it in my oil before tearing it down to do the guides and at 116k miles the inside of my engine looked new. Now the smallest amount of sludge anywhere.




O.p. if you want to use it go ahead and use it. This is the first negative seafoam post i have ever seen. As i stated above, worst case scenario nothing happens, and thats because your car was already clean.

Sea Foam solves a problem from the past that simply is no longer an issue. it probably won't damage anything, but you won't get any benefit either. if it did work, it would already be formulated in the gasoline that you buy.

Modern petroleum is so highly refined and the additives are so good that you will not get varnish and sludge building up, so long as your engine is in proper working order.

Deposits in modern engines are the result of non-hydrocarbon contaminants that Sea Foam will not address, such as sodium and zinc.

I used 2 cans of it on my MR2 Turbo. 1/2 a can in the oil, other 1/2 in the intake via a vacuum tube and 1 can in the gas tank. It did a wonderful job cleaning the sludge in the oil like Topaz stated. I added it right before an oil change and the oil filter must have weighd 5 lbs. I got the car with 60k and decided to add seafoam at 90k. The car had no catalytic converter just a 3" downpipe from the turbo so i wasnt worried about destroying cats. I used it as a last resort to address a low idle issue when replacing everything associated did not work. Seafoam cleared up whatever crap was in the engine and since I was not the original owner it most likely did not go through regular maintenance like I have done with the car. Car ran great and trouble-free for another 30-40k miles being spiritedly driven boosting 18psi on a stock engine before selling her.

Interesting discussion.

FWIW, I've had good results from using SeaFoam in the carbs of old Honda motorcycles.

I also cleaned out the intake system on a '93 Plymouth minivan by using the method described here: http://www.nicoclub.com/archives/how...right-way.html After adding it to the intake maifold, the oil was BLACK. Changed it and it ran great. I won't say it made a night and day difference, but it did run smoother.

Eparayno, is that a pic of yourself in your sig?

Seafoam in the intake is supposed to lube the tb, remove deposits, and clean the cats.

Doesnt hurt to try it out. It prob works best on a car that has been sitting for some extended period of time.

I recommend Chevron which has Techron in it.

Someone once posted a list of top tier gas stations.

Straight from one of our consultants who worked at a major petroleum company:

They are all the same, the differences are just marketing.

They all basically use the same detergents, due to the market size and cost pressures, there simply aren't that many choices of effectives additives.

PIBSA (Polyisobutylene Succinic Anhydride) is cheap, very effective and not covered by any patents currently.

The major gas companies would like nothing more than for you to continue believing that their products aren't completely interchangeable, but the fact is they are.

I've got 5 bottles of it.
I've been using Mobil 93, Sunoco 93, and Hess 93 octane for almost all of my cars 137K miles. I use 3 to 4 bottles of Techron every year.
Works for me, I've seen a few post of what the back sides of intake valves look like on these forums and they aren't pretty.
Here's mine after 100+K miles.

I'd be interested to see the same pic of a Seafoamed engine. I doubt it would be as clean as the one that uses Techron in the fuel tank (shown in pics above).
Never used Seafoam, but I do change the oil and filter every 7500 miles, BMW synthetic 5w-30 for the first 130K then just switched to Mobil1 0w-40.
These pics are at 132K miles.

I foamed the oil because i didnt know what to expect when i got it open. Other than all the metal cases being tinted orange on the inside it was like new.

For those trying to suck seafoam into the intake....what are you using for an intake suction port? I used it on my `96 Volvo 855 T5 (with xcelllent results, btw), but that car had a vacuum tree mounted near the throttle body.

Should state...the engine is an M62B44....

thanks

Use the passenger side small vacuum hose on the back of the intake (OSV/CCV) will do. If you buy the spray can version of Seafoam, spray behind the throttle body butterfly valve.

GM Top Engine Cleaner...similar product

General Motors makes a similar product, GM Top Engine Cleaner for the cleaning of intake system and intake valves of carbon deposits. They products do work, but unless you are having a problem that needs to be resolved, I would avoid them. I don't believe you should use them routinely for maintenance.'

Use Top Tier gasoline:http://www.toptiergas.com/

Perhaps occasional use of a fuel system additive such as "Shell V-Power", Chevron Techron, Lubro Moly or one of the other quality additives.
