Sea Foam before Oil Change
Hey D2 Owners,
On Feb. 17, I have my D2 going to the shop for an oil change, transmission fluid and filter service and fuel filter change. I have the fuel filter and would do the change myself but recently it seems where I live getting above zero degrees is near impossible. So I will have the shop do it since it will be on the lift.
My questions are:

My questions are:
- Has/does anybody use Sea Foam in their crankcase prior to an oil change?
- Did you notice any results; extra crude in the oil during the oil change?
- A smoother running engine after the oil change?

As for Sea Foam: If you've always used 100% synthetic oil (as you should), there is not likely much to clean out...if you've always used "dino" oil, you may actually cause oil leaks.
And be aware, as I've learned from removing the oil pan and baffle, several ounces of oil are left in the engine with a normal drain...all the SeaFoam will not be drained with a simple change. I'm unimpressed with Audi's design that leaves so much in the pan and baffle.

Good to know about the remaining oil issue. I've always used SF as a gas treatment but I think I'll pass on using it in my crankcase.
The AT-205 Reseal sounds like an interesting product. I'll have to check it out.
Thanks for the advice silverd2.

Seafoam is basically Kerosine, it functions as a solvent. I would not use it in my oil because it is very harsh on gaskets and hoses. Now if I knew for a fact that I had sludge buildup (unlikely with synthetic, or even conventional if you change it as you should) then I might add something to help dissolve deposits. As far as that goes, I've had very good luck with marvel mystery oil. I only used it on one very sludged car, and in just a few minutes it had dissolved the gunk, and it drained nicely. If sealing gaskets is a priority, the blue devil stuff works great. It's a very runny liquid that swells seals nicely. We used rear main sealer with excellent results.

I've had this thought in my head that products that soften up rubber seals will ultimately lead to wear... Do you have an insight into how they work?
If I wanted to use a product like this myself, how would I "sift the wheat from the chaff" with these products betting my bottom dollar that I can't get 'AT-205 Reseal' down here!

Sam, I've always been a bit dubious about seal reconditioning products. Do you rate them, or just specifically AT-205 Reseal?

As I understand it (and some personal experience), it's true that most products simply swell and over-soften the rubber through "unnatural" processes, providing a quick temporary fix followed by early failure.
My best success with AT-205 was with a high mileage Passat V6 that was using (not leaking) a full quart of oil every 1000K miles through valve stem seals...after a 500 mile treatment, usage dropped (until I sold it years later) to .3 -.4 qts per 1K miles.
I've also used it on all other rubber products like door seals, a previously leaking tail light gasket, o-rings, lip seals, etc..with good results with all...even restoring and extending the life of windshield wiper blades.
I'd do a commercial for em...think I just did...where's my check?

G'day Sam,
Does this sound like a similar product to your AT-205 Reseal:
http://www.nulon.com.au/products/Engine_Treatments/Engine_Stop_Leak/
Nulon are quite highly regarded in Australia, and I use their synthetic oil in my A4.
(The S8 currently has Penrite 10W50 synthetic, as it was on special - 2nd 5L half price )

Here's a link to a discussion with other links to AT-205's chemical make-up, so maybe you could compare to other products >>>

I'm a BIG fan of Marvel Mystery Oil. Both in fuel and oil. Marvel works great and has the advantage of being very reasonably priced. If you run diesel, I would not be without it. pc

I used Seafoam in my crankcase and in the tank 500 miles prior to oil change. I have always run full synthetic oil. The car seemed a little more responsive after the seafoam but nothing major. About three months later i got a chance to drive at about 100 -110 mph on cruise for about an hour on a road trip. Ever since i got home the car is like never before, way more power. I even had a sticky lifter quiet down.
