I have read posts and seen DIY's on using Sea Foam to clean out your engine...

and wonder:

Is this a recomended/usefull practice?
How many do this? have done/tried this?
Does it actually work?
What are the benifits?
Is it harmless?

Thanks

Doubt you'll get a consensus on this.

There are some who swear by it, other's who've had problems after treatment (fouled O2 sensors, plugs, etc.) Frankly, my own opinion on these kinds of treatments is if you have a problem and think it might help, go ahead and try it. On the other hand, if your car's running well, I wouldn't think it's a wise thing to do as a maintenance item. If there's a potential downside of creating a problem I'm a big believer in the axiom: If it ain't broke, don't fix it. I'm sure others will disagree, but that's my 2¢.

judging by your car , a 2000, go do it.

My opinion is, do it when the car is rather new like 50~70k so that there won't be so much crap coming out to foul out the plugs and the O2 sensor.

I own a CPO that had an accumulation of carbon, probably from a history of excessive idling, use of drive thrus and poor gas.
Pull on this is brake vacuum hose. It will pull straight out of a rubber coupler in the brake booster. No need to undo clamps. I use a funnel to dump a third of a can of Seafoam into the vacuum hose.



I shut off the engine and let it sit for for about 40 to 60 min and then start the engine. The white smoke shows there are carbon deposits burning off.
It helps to have a code reader to clear codes, but they will go away themselves after a couple of days. So far my O2 sensors and spark plugs are unaffected. The engine runs more smoothly after Seafoaming. If there is a lot of white smoke, its OK to Seafoam again of a few days.

It cleans the varnish and sludge from your valve train, etc.
There are a number of ways to use it. Add it to your oil, add it to your gas (where it will clean fuel injectors) or have the engine ingest it through a vacuum tube. Or all three.

For cleaning sludge, several here have been recommending AutoRX, which works in a slower, perhaps safer way, as an oil additive. It takes several miles and a few treatments requiring use of dino oil and, of course, changing your oil filter...
For complete details see
www.auto-rx.com

You might want to take a look under your valve cover to see if you really need it, first. Also change your oil and oil filter afterward, the sludge has to go somewhere, better to go out the oil pan drain.

For preventative maintenance of the fuel injectors, I think its best to 1) use good quality detergent gasoline, 2) add Techron to your gas tank a couple times per year, but you can throw a 3rd of a can of Seafoam in your tank.

i've used it. no problems. it confused the ECU for about a week. one tank i got nearly 42mpg, the following i avged 19. now im back to ~26/27
it was easy. smoked alot.

imho, it was like one of those "snake" firecrackers. you light it on fire, its really cool for a few minutes, after that.. its just something you did. nothing special.

Sounds like a problem to me.

Before using any kind of monkey milk like this, ask yourself a few questions.

1) What problem are you trying to solve by using this product?

2) Do you have any evidence that using the product will actually solve the problem you have?

3) Shouldn't the bottle have a picture of Dale Earnhart Jr. on it?...

it wasnt an ongoing problem. thats what i was implying. the gas mileage was a mere inconvenience for a week.. but the fact that it removed a bunch of unnecessary carbon deposits outweighed it.

I've used it many times on all my cars. If the car has less than 75k miles though, I wouldn't use it, just because it probably doesn't need to be used.

Use it if you want as much maintenance for your car as kpeng for his. I never used it and my car needs nothing beyond extended standard maintenance.

I have never used it but I saw a report on nightline (i think) where Jiffy Lube was selling it as one of their services and the cars engine went out afterwards. They actually said several cars had engine failure after the treatment. In other words, Jiffy Lube approved means a big NO NO for me. They said that chunks of the broken deposits go into the more delicate parts of the engine and ruin it or clog up sensors. This is just info from that report, im sure that this has worked for some people but im not willing to buy a new engine as an experiment just yet.

I've seen the same reports on that stuff.......... you take your chances using it. After seeing the reports......there is no way I'd use that stuff. Not willing to try something that could ruin my engine......

Thanks for the input--Too much risk for little benefit

Doubt you'll get a consensus on this.

A few responded with about a 50/50 split but I agree with you here.

In my ole POS 99 b2500 I wouldnt hessitate trying something like this.

BUT I LIKE my BMW engine. With 120k on it, it runs very well, fires up hot or cold before a full revolution, is responsive, and gets a consistant 26-30 mpg. :bow:

I have seafoamed and deepcreeped my car. No issues whatsoever. Actually I lie. The only issue I had was when I tore the intake boot hose or some **** and my car would throw a running lean in bank 2 error code from time to time. Had that replaced and everything is running great. I performed a number of maintence procedures around the same time such as new plugs/ccv gasket/other things I can't remember. Car spewed nasty white smoke forever it seemed. Runs fine though after. It is a risk but from all the reading I did it seems its relatively safe as long as you pour it into the right spots and don't rip hoses like I did.

Edit: Didn't notice any real gain in performance or gas mileage to be quite honest. Definately made me feel better though knowing all that **** coming out my exhaust was from the internal cleaning.

Why does everybody think the white smoke is the gunk and carbon in your engine burning off, its just the seafoam burning, and I used it in my 1990 jeep cherokee 4.0 when it had about 215k miles on it, poured it right into the throttle body because my brakes are electric not vacuum boosted, it did absolutely nothing, in fact my engine started knocking pretty bad a couple weeks later but thats probably just because its really old and worn out, but that was like a year ago and it still runs, sounds terrible.......but runs.
