if its in the crankcase, how long do I keep it in before I change the oil and or filter?

I usually follow the printed instructions on the web:

Another testimonial... a SeaFoam overnight cylinder soak is standard procedure for '92 - '99 Saturns with the 1.9L. There was a widespread problem with the oil rings loading up with crud and seizing in the grooves. An overnight soak on mine reduced oil consumption from a quart every 500 miles to a quart every 1200 miles. I then put the rest of the can into the crankcase for about 100 miles, changed oil. Consumption was down to a negligible amount between changes. Many similar stories in the Saturn world.

hi, thats exactly what I wanted to know. many thanx.

Recently used it on the Explorer with great results, 146,000 miles on it and it did the trick... as mentioned, do NOT do this in a garage... quite frankly, I wouldn't do it any a community... unless super late at night... it produces a LOT of smoke... I was apprehensive, but it did indeed work.

Here is a good read on the usage:

I asked a while back on the turbo Forum about it. I was worried sucking it in through the intake would cause and issue with the turbo. I had my cylinder head refreshed so it doesn't need to be cleaned out now.

My two cents.... "kinda sorta" snake oil. The naptha is a solvent and will work like other solvents in the oil and seafoam can be beneficial if used as directed... but is nothing magical

On a hot engine, you can slowly introduce a very small stream of distilled water into the intake. Both the water and seafoam will be converted to steam during combustion and will clean out the piston tops, possibly rings and downstream exhaust, and both will produce a fine cloud of white "smoke" from the tailpipe

the same piston soak procedure is done with other solvents, too, quite often Marvel Mystery Oil or GM Top End Cleaner

I did a seafoam soak and it did nothing for my #1 cylinder, but an overnight with pure acetone helped.

You can buy a 32 oz can of pure naptha for $6~10 and make your own seafoam

I had hard starting and a rough idle until warm up on my 83 944 (98k miles) from it sitting for 14 years with very minimal starting. Ran 3/4 can of Seafoam through the vacuum system, smoked out the neighborhood, took it for a hard drive, viola, runs excellent and starts up very fast. No hesitation or rough idle on cold motor. Do it!

On the other hand, I tried it on my 02 330i (132k miles) and didn't notice any difference.

Gentlemen: AutoZone generally carries Seafoam on the shelf. I am not plugging either this chain or the product, but I have heard from many, many people who have used it have all given positive feedback on it's use. You can put in the gas or the oil. It will give off loads of white smoke while it is being used. I personally haven't ever used it But I'm about to on my 04 Ford exploder with a 4.6 in it.

It will only smoke if you suck it in through a vacuum line, not in the oil or gas.

I think a couple of these guys were overseas where it is not so available.

Seafoam is great, but word of warning. If your gaskets are old and you put seafoam in the oil, you run the risk of it eating a bit of your gaskets and causing a leak. This is what happened to me. Works great on the intake though. Highly recommend it.

Cole

It's not eating your seals, but rather clearing sludge away from a bad seal and allowing it to leak.


If your car is at that point of neglect those items should be cleaned up and fixed!
