#17 of 19 2004 VW Passat Turbo Oil Sludge
Mar 09, 2010 (8:16 am)
I have an 04 Passat Turbo. I was told by a VW dealer I should use a full synthetic instead of the semi I am now. They also told me if I were to switch from a semi to a full synthetic that they highly recommend me to do a flush, I think they said engine flush. They said to do this because the my car was prone to engine sludge. They told me it would cost me $400 for this flush! How important is it to have this flush done? I know there have been many complaints on here of the oil sludge problem, but do I really need to do this flush?

Hi - I'd review the forum here that covers oil sludging issues. It's at http://townhall-talk.edmunds.com/WebX/.f0aef02/369!make=Volkswagen&model=Passat&- ed_makeindex=.f0aef02.
If you check your manual, it should show that the ONLY oil you REALLY want to use is a VW certified 5W-40 or better. I know there are several experts on this forum (altair being one who comes to mind who gives very sound advice) who will direct you to the official list from VW. I believe if the bottle says it's VW 502, then you're good to go. You definitely don't want to use anything "less" than that, like a partial synthetic.
As for cleaning the engine, I did find a product online, Auto-Rx, that supposedly will take care of the cleaning for you, and I believe you can pick up the necessary product for $50 - $60 if you check their Web site. I've ordered some for my 1999 V6 Passat, which is sadly now experiencing other issues.
Sludging can kill your engine, especially with a turbo. Full synthetic might cost more, but it's worth it.

must meet VW 502.00 and two most easily available oils are Mobil 1 0W40 and Castrol Syntec 0W30.
