Seafoam works.

HOLY FREAKIN CRAP. Anybody else ever experience the dreaded flashing check engine light while doing this? lol. Think maybe my dad was pouring it in a little too fast.....It smoked up so bad into the engine bay that I had to shut it off so he could breathe and stop pouring!

But WOW, did that thing have balls after that. 95 miles an hour on a mountain road, and that car was hardly even pulling hills a week ago! And smooth? Smooth doesn't even begin to cover it.

Not going to breathe a word of this to my friend/mechanic....I texted him to ask him about it beforehand and he said it could be dangerous, and he wouldn't if he were me.

Is there any downside to using seafoam? Possible damage?

I read one post where the person indicated that the seafoam reduces the effectivenss of the
oil in lubricating your engine. Sounds plausible. In many other posts it sounds like the seafoam
user has a born-again engine after the treatment.

There seem to be quite a few questions on exactly how to add it to the intake. Maybe the
experts will do a youtube video showing us how to do this for an 850.

An 850 or not, I don't really see what would be the difference.
There are many youtube videos on this.
I too have read only one negative feedback and a thousand positive ones.
If you don't like the oil after the treatment, change it right away.

Good luck.

I think the only way you'd be able to damage it is if you simply suck it into the engine too fast and bend a rod or something. It doesn't really reduce the effectiveness of the oil, but it cleans out all the passages the oil runs through, and dirties it up quite a bit - mine was jet black coming out after 4,000 miles, normally it's still a brownish color after 5,000. I'd change the oil within a few days of adding it - I wouldn't go more than 100 miles or 3 days with it in there. Once you suck it into the intake, I'd change the oil right after you finish driving it.

There's tons of youtube videos for other cars, the procedure's almost identical. I pulled off the (only) vacuum tree hose on my car and sucked it in right there.


Let it suck in a little bit, let the engine speed recover, then go at it again a little bit at a time. They say to let it have it all at the end and stall the engine, but mine wouldn't stall, so I just switched off the key and let it sit for 15 minutes.

Then start your car and let the idle catch - mine stumbled around for a few seconds, and then go drive like a maniac and blow all the crud out of it. I think it's a good idea to keep it in 2nd or 3rd gear and keep the RPM's up while you drive around, put your foot down in it and give it the old Italian tuneup. The more crud you blow out, the better

I can definitely tell an improvement. I haven't experimented much with it, but it feels like it takes off from stoplights and with the A/C running with a lot more enthusiasm with a lot less gas pressure.

Friday is fine. I just do a lot of driving
