For people really interesting in oil change intervals, please go to the original thread at bobistheoilguy.com under oil analysis diesel auto, and READ.

First off, the guy used the wrong oil. Second, the evidence is clear that he has a coolant leak into the oil that ruined the TBN. Third, he probably never changed the bypass filter at all and that's why the wear metals are so high.

If not for those two mistakes, and a coolant leak, he'd be fine. Of course, it is a VW.
