Hello Uber
Uber, your persistence and confidence made me do some digging. You are right. The dealer gave me the wrong information. I went to the dealer and requested to see the type of oil they use on diesels. This is what they showed me:
It appears I was given the wrong information. All is safe and DPF will live on. This is part of the reason oil analysis showed properties similar to 0w30.
Thanks for clarifying.

Notice the high phosphorus/zinc readings....
There's a ton of great info here on Audiworld, make you own decision on the correlation. My experience is posted just to say that as one who followed the breakin and first oil change and is not having excessive consumption. What I remember of these decade-old discussions is that of the people complaining of excessive consumption, many/most had changed early. That doesn't mean that everyone who changed early had problems, just that it appeared that there was a strong correlation between having problems and having changed early.
One theory is that modern machining tolerances are so tight that rings *NEED* those suspended metal particles to seat properly. I'm an electrical engineer, not a mechanical engineer, so I'm staying mostly out of that. Search the forums, read the postings, make your own decision - just make it informed, not based on 20-30yo conventional wisdom. YMMV, professional driver on closed course, etc, etc, etc.

It will be nice to see the OP's next oil change printout, I would guess the phosphorus/zince levels to be much, much lower.
