"Seafoam" to remove carbon deposits
 

Just watched Utube about some seafoam to remove engine deposits. What is it?
Where to buy it?

Just do a search for "seafoam" on this forum, lots of discussion about it.

You can get it at NAPA or Carquest. It can be added to fuel or oil.

It's actually pretty good. I use it to decarbon marine engines in very high seafoam to fuel ratios (like 1 can in only 5L of fuel). I don't know if I would recommend that for your audi though, but it works great on 2 stroke marine applications.

It comes in a liquid or pressurized spray container. It does work for removing carbon buildup (to some degree). If you can bleed some into your manifold through a vac line you'll find that the most effective. Do it outside in an open area because it will fog out your entire neighbourhood in white smoke.

not applicable to your A4 really. I wouldn't concern yourself with it.

If you have a car with fuel stratified injection...and you believe deposits to be hurting your car, then consider looking deeper into it. Till then, not a concern.

My FSI 3.2 has 76,000km on it and has never had the carbon deposits removed by any means that I know of (2nd owner). I'm pretty much right on the factory posted 0-60 times right now so I'm not really sure how much clout these "carbon buildup is horrible in FSI engines" claims actually have.

I guess I'll just have to pull the intake manifold and find out.

However, with that said, there is no harm in running a seafoam decarbon procedure on any car. It will always do more good than harm.

GOING to NAPA right now. Stand by for smoking the neighbourhood pictures

Re: "Seafoam" to remove carbon deposits
 

They'll be good ones. Some people say it's the carbon burning off but I'm pretty confident its a mixture of carbon burning and the seafoam itself burning. It doesn't stink all that bad but it produces TONNES of white smoke...

Another interesting point, when I run it in high concentrations on my Evinrude 140 looper 2 stroke I actually pick up 200-300rpm at the top end and a couple extra MPH running up the river. SeaFoam is volatile stuff...

Looking forward the the you tube on this one!!!

Just did the Seafoam and Deep Creep.
Poured it all down the air intake and on the K air filter.
Is it the right stuff?
I do not have a puff of smoke at all. There are nasty looking droplets of brownish black wet tar at the end of exhaust.
I used Techron in July so maybe I did not have any deposits.
The car runs better.


PS
On the new Tide Commercial (with the green shirt) who would you pick mom or daughter?

I'm not sure pouring it into the air intake was a good idea, I believe there are O2 sensors in there that shouldn't get oily.

The best way is to get it into the manifold through vac line. Also, on a hot engine, you can pull the plugs and deep creep the cylinders - turn it over with the plugs out so you don't hydrolock. You may get a code you have to clear afterwards.
