I did the treatment yesterday, about 5oz in the vacum line and 5oz in the gas tank. Not as much smoke as I anticipated. I guess thats a good thing. Very easy to do.

 

My understanding is that you are also supposed to pour 1/3 of the bottle into the crankcase

 

It doesn't matter. Because it's magic.

 

complete waste of money...does absolutely nothing...youre lucky you didnt damage your car

 

++ 1.
The true way to clean is to remove parts and clean them in solvents and or sand blast.
Pour your problems away is kinda like Dr. Wizzo's Magical Fat Removal Exlir.
Often the pour your problems away solvents may help some areas but foul others like hoses.
Buyer Beware !!

 

How many miles do you have?
I did mine at 75k and had a good amount of smoke.

 

Would you put Techron by Chevron in the same category? That product seems more legitimate, but could just be a marketing gimmick.

 

It's all snake oil

 

That's no way to talk about sea foam. It's magic.

 

youre gonna burn smoke either way. the "seafoam" is a petroleum product. the smoke produced tells you nothing about whether your engine was "dirty" or "clean".

and feuss i love you! toooooo funny

 

Waste of money but if it makes you feel better than go for it. I would NOT put it in the crankcase, fuel tank only if you choose to use it.

 

I've used it in my civic's b16. If you put it in the crankcase, it's suppose to be right before you do an oil change. The reason is because it thins out the oil a bit. And if it does loosen contaminants in the crankcase, you wouldn't want to keep running your engine without cleaning it out. I really don't think it did anything btw.
I would never use or put seafoam in a k series engine with our timing chain possibly stretching issues.

 

I read somewhere that seafoam fouls up your spark plugs as well. So if you're gonna do it, do it before an oil change and before you plan to change your spark plugs.

Controversial topic, this seafoam is.

 

this is true.

also true.

we've hit the tri-fecta!!!!!!

 

I thought it was good for cleaning out the fuel injectors. I had a slight hesitation when cruising at 2k rpm. Just got done using seafoam(in gas tank) and after I change my oil and check plugs, and air filter, I'll see if its better (could be the air filter too though). I just bought the car with 150k miles on it and wanted to make sure everythings g2g.

 

Sea foam doesn't work huh.. Lol okay.. I've seen it, I've witnessed it!!! And it worked.. And by the way that was on my rsx type s, 130k miles. K20 engine!

Idles better, sounds better at idle.. Isn't as loud at idle..isn't loud in the morning anymore.. Smoother everything!!! I'm not saying everyone is going to see great results but I did 100%..

And the smoke is from carbon buildup right, so the more buildup you have the more smoke.. I had a lot of smoke come out!! I also got an oil change within 60 miles after..

I just got an 05 TL, and when the time comes for an oil change, guess what

 

^lol Rock on bro. Too many factors control the behavioral improvements you listed. Seafoam is magic in a can. You're better off using Lucas fuel additive every so often.
