Anyone ever try seafoam?
 

Seafoam is this cleaner you can put just about anywhere in your car; in the engine with the oil, in the gas tank to clean injectors and raise octane and the best is to suck it up through a vacumn line and fog up your neighbourhood :rock: . Anyways, I'm just wondering if anyone else has used this on their 8 yet. It's supposed to clean out the spark plugs too.

I have yet to try it on my 8, but I used it 2 months ago on my 95 volvo 850 with 168K miles. sucked half of the bottle through a vacuum line coming from the TB and shut the car off. 20 minutes later, went back out to start the car up and take it for a 5 mile (VERY SPIRITED) drive. Clouds of white smoke were pooring out of the exhaust for the first 3 miles. after that it went away. I felt like spy hunter with all the smoke htough. Completely cleared up a rough idle issue I was having and restored 1-2mpg on my highway trips.

all in all I am very impressed and have done this treatment to a half dozen high mileage cars. all with good results.

i've used it at a few oil change intervals to clean things up...
the vacuum line pour is sweet! lots of smoke!! can't say it really helps anything though... i'm gonna get me some bg44k for my next cleanup to try that out...

I have used seafoam in the past but not on a rotary. Which vaccum hose did you use on the 8?

brake booster

Me too! Worked in the past but don't know about these modern cars.

don't see why it wouldn't work the same. i used it a lot in my Rx-7 and i plan to use it in the Rx-8 as well.

Im contemplating on doin' that as well. maybe next weekend...

Mazda-Rati, I was actually advised against using Seafoam on high mileage cars. The thinking was that if there's places where seals or gaskets are iffy very often the only thing preventing leaks is carbon and crap build up. Glad to hear it worked good for you though, maybe that advice was just being overly cautious.

The results could be different from car to car. Some cars I've used this on, the owners have noticed a difference. Others notice none, but I have yet to use it on a car and see problems with the engine. I work with a guy w/ a 95 jeep cheerokee w/ 254K on it. The owner swears by seafoam. uses it every 30K. Just did it on a friends 03 Avalanche w/ 130K. his truck is still running fine since I spoke with him a few weeks ago.

I caught on to the hype over on the volvospeed.com forums if anyone cares from some reading material http://volvospeed.com/vs_forum/index...opic=20144&hl=

Anybody try it yet?

ahh, the good ol' magic elixir to the rescue, would you be interested in some Miracle Tonic too?

snake medicines have changed over the years, but the suckers stay the same ...

I take it that means no one has tried it. So what do we use to clean out the carbon and gunk build up ( i'll search right after this post lol )

I've got first hand experience with that. Not Seafoam, but some kind of snake oil.

Back in the mid-60s my brother had an Olds 98 convertible. Great car - black, wide, smooth riding, great pickup. (Not just acceleration, either.)

Anyway, there was a little bit of tappet noise. A pump jockey said "I've got just the thing for that," and sold us a bottle of snake oil. We poured it into the oil, and revved the engine.

Big puff of smoke out the tailpipe. From then on, the car burned a quart every couple of hundred miles and was just never the same. We realized immediately that sludge had been holding everything together.

i've used it once in the 8 now. don't really plan to use as often as i did in the 7. honestly, i don't see any point to using more than maybe a few times a year until the time starts to show the engine's age.

I hear that stuff is like Jesus for your engine

I'm 1 for 2 with miracle tonics. Long time ago had a transmission that was starting to get a bit flakey and some mechanic gave me a tube of what he called "Whale oil". Tranny died a week later. The other time was a V8 that was making a miserable racket and no power. Fellow I knew diagnosed stuck valve and said run a quart of kerosene in the oil for about 20 minutes then do oil change. Worked like a charm!

As far as carbon removal in the rotary, there was a thread some time ago from someone who used plain water through the vacuum line and claimed that was all you needed.
