Has anyone tried sea foam cleaner?

[stillhunter]

Talked to a friend he said he was going to try sea foam engine treatment that goes into the crankcase with the oil.Has anyone tried this.I'm afraid it could do more harm than good

[Nick762]

I don't trust it.
But I dont trust much haha

I will add some to my gas if I'm out of Startron, but the only thing that goes in my crankcase (cars and toys alike) is oil

I use the stuff in every engine I own. Fuel, crankcase, and if it has one brake booster line.

If you run it in your crankcase. You'll want to change oil in about 30 miles of driviing.

I have never been a fan of 'mechanic in a can' products myself..

My opinion is a regular oil change regiment will mean never needing to use a cleaning agent. And if I get an engine that hasn't been serviced I do a couple back to back oil changes and sometimes just a small amount of ATF to act as a detergent in the 1st change.

But too much detergent will dislodge all the gunk and sent travelling around in the engine to block oil passages and possibly do more harm than good.

Seafoam is just pure petroleum. Pretty much every Seafoam product be it regular Seafoam, or Deep Creep, or Trans Tune is just pure petroleum. It's purpose is to clean all that gunk out and leave it in the bottom of the pan so when you change oil within the 30 to 50 mile mark after you add it to the crankcase it will pull all that nasty stuff out and you put fresh oil in and it's like a brand new motor. When you add it to fuel it cleans your entire fuel system from varnish and water deposits. Cleans out gummed carb jets and injectors. When added to your tranny it will break any build up and leave it in the pan. You also have to change tranny fluid when you do the Trans Tune.

I usually run it in all my small engines regularily and in my vehicles usually once a month in the fuel.

I only do Trans Tune, Crank Case or Deep Creep treatments as needed. Deep Creep is sensor safe spray great for intakes and cleaning carbon buildup. And a very good penetrant too.

Dude you sound like a commercial, do you own stock in Seafoam??

I actually broke down and ran a ½ can into my 1997 F150's brake vacuum line a few months ago after realizing that my EGR was plugged up. I followed the instructions and when I started it up the crud that came out the pipe was unreal. White smoke, chunks of God only knows what etc. It ran awful, knocked, pinged and was gutless for about 15 minutes. Then it cleared up and I drove it 140 miles home. The next day I put the other half of the can in expecting the same thing to happen (I figured it was the Seafoam that was smoking out the pipe) but nothing happened other than a bit of an odd odor from the pipe for a few minutes. Whatever gunk was in the intake/ pistons seems to have come out with one use. I've run it in the fuel system as well, but I don’t think I’ll ever put it straight into the crankcase.

I've never added it to my oil , but I swear by Seafoam in my fuel system .
I use it in everything I have that runs on gasoline.

[Stingray]

I tried Seafoam in my gas for my Ford truck after a recommendation from a friend. He said it would clean the injectors.
After a quarter tank my truck ran smoother and felt a bit more pickup. And since it improved gas mileage two miles per gallon I now add a can of Seafoam to a full tank every two or three months.

I wish I owned stock. You just can't argue with proven results. Fuel lasts longer on the shelf with Seafoam in it also in my experience.

It's great for de-carbing 2 strokes. I've used it in my 200 Johnson outboard many times. Just bring the engine up to temp and squirt the seafoam in the carbs with an oil can until the engine dies. Let it sit 10 minutes, fire it back up and hope the neighbors don't call the fire department cause it's gonna smoke... a lot!
