Sorry, I didn't mean to imply that there's been any problem with my A4. I'm
using the specified synthetic in it and it's been fine. Only to say that the
whole sludge thing is not unique or even uncommon in the turbo 4-banger
world (4-banger--did I just say that on an Audi list ;-) and that it has a
fairly easy solution.
