I read alot of the MK8 posts about seafoam treatment for their cars and I was wondering If anyone tried it for their LS.
 
JohnnyB did this to his car not to long ago.. You might want to PM him to see how it went..
 
I ran some seafoam through my car last week. It is idling much smoother now. I've been using seafoam for about 4 years and have always been pleased with its results.
 
Lincoln does not recomend any oil or fuel additive in LS. If still under warranty I would carefull what you add.
 
I have never heard of this stuff before, granted I am new to the inner workings of automobiles but still, this stuff sounds pretty damn good.

Any other known drawbacks to using this besides possible warranty issues?
 
I've heard some people swear by it.
And others... well I know someone who ran seafoam through the vacuum line and it killed his O2 sensors.
 
I scope out a Dodge forum every now and then because of the Intrepid and they use that stuff alot over there. If you put it into the gas it supposedly makes alot of smoke come out the tailpipe. To me, i think Seafoam falls into the same catagory as Slick 50, octane booster, stop leaks and all that. Yes it "should" have a positive effect BUT you also shouldnt have a need to use it. Between the oil required and using premium gas the LS should stay relatively clean if maintained correctly.
 
yeah my idle is little rough, and it's kinda a car peeve of mine (since a lot of my time is spent in line at the drive -thru:D ). I think I'll give it a shot too
 
If you do end up using the stuff give us some feedback. It sounds a little too good to be true. I would feel a little funny adding the same product to my oil and my gas tank.
 
Yeah it is a little strange, but then again that's what I thought about the .99 chip that increased my horsepower 20%! haha big just kiddin on that one, it was only 15% ;)

Marvel Mystery Oil is the same way, you can add it to both.
 
Actually the "smoke screen" occurs when you remove a large vacuum line like from a brake booster and pour an ounce of this in. It gets run through the intake and cleans valves..etc. HUGE SMOKESCREEN!

On the Yamaha XJ motorcycle forum this stuff is like the fountain of youth. It cleans engines up VERY WELL, improves performance and doesn't cause any negative effects. You can find threads for this on almost any auto enthusiast site. I've seen it here, on the Yamaha site, on my BMW Z3 site, and on a Mitsubishi Eclipse site. I haven't heard anything bad and lots of good. That said, I've used it in all my cars, bikes, and boats.

If you put in the crankcase just run it for about 10 minutes. Let it sit. Run it again long enough to warm up and drain well, then drain the oil and replace.

Your results will depend on how nasty your fuel system, crankcase, intake, etc are to start with. In LS's running good premium gas, and HOPEFULLY regular oil changes, I wouldn't expect miracles, but it's got to help!
 
I'm not so sure that it would be very effective in the oil/gas tank. But I know that sucking it through a vacuum hose is a VERY good way of cleaning the intake tract.

And it's not some kind of crazy procedure done with some kind of warranty-voiding snake oil. Dealers use what is essentially the same product (they call it "top end engine cleaner"), and I have seen TSBs issued by GM and Honda that explain how to address carbon buildup problems by using the exact same process.

I have used it on many different cars. One set misfire & O2 sensor codes because the cleaning process caused the engine to misfire, and the O2 sensor to give unexpected readings. That's probably where the stories about sensor damage come from. But after clearing the codes, they never recurred.

This is true. I forget what Chrysler calls it but its essentially the same thing as seafoam. I am sure whatever the fuel system cleaner that the Lincoln dealer offers is also the same thing. Yes the brake booster will create a nice smokescreen that your neighbors will love. I feel the need to add a word of caution as i know the LS is very touchy. I have heard that when you run it thru the intake (pcv,brake booster) its wise to change the oil afterwards. I guess a small amount is able to still get into the oil somehow and you definately dont want to keep it in there long term.

I just did a search and found a link to an Audi site that gives a good How-To.

I swear by this stuff, my last car used it before every oil change....I love Seafoam....

I use it in the LS as well...
 
I have been on the fence about using it, for my '91 v6 Sable anyway. I know the car could use a good cleaning, just was not sure how you really go about it.

I use it in the crankcase about 500 miles before oilchange...As well as in the gas tank...

Some use it through thte PCV system as well...
 
Yea, I am probably going to do that once I have it running good, been slowly tuning it up here and there, probably gonna sell it once its all done.
 
I have friend in the SHO community that swears by this stuff. He said it will even un-gum(new word) the oil rings.

I will be getting some for my SHO, I have little blow by and he suggested the stuff. Not to mention.... the way the motor is designed, I get build up on the secondaries.

when I worked at the ford dealership the tech would use something very similiar when they did a full fuel system cleaning. They would take the cars out into the yard and it would produce a huge smoke screen. and it stinks something funky.
