LOL
nice .2 on the insolubles... what oil filter were you using?
did you add a bypass?
Awesome report.

Good start, with very nice results.
Extending the OCI?
Extending the OCI?
Wish there was a TBN to know how far is too far.
I wouldn't worry about TBN here, many many UOAs on TDT and T6 and most other diesel oils show TBN is generally good out to 20k miles or more.
For example:

Apparently this oil doesn't have any molybdenum. Anyone else notice that? What about adding a moly additive?

Adding snake oil to a high quality oil like the one used would interfere with the function of the additives pack. If this oil needed some moly, Mobil would have added some.
Liqui Moly themselves don't even use Moly in most of their better synthetic oils, although they still sell cans of it for folks that think it will help.
The UOA is near perfect although it would be nice to know what the remaining TBN is and it demonstrates that you don't need fancy VW approved oils to get good results, just a 5/40 with enough Zinc.
I suspect this engine has an easy life of mostly highway use in a clean air environment, as the Silicon and Insolubles are very low, unless it has a bypass filter.

I thought vw engines shed iron like crazy? Guess not this one.

I've seen a lot of VW TDI UOA's and this is probably the best one. Must have been all highway, no cold starts, clean air and driven like a Granny, using good oil and filters.

Because it does help as my mileage and equipment has proven. Get off your soap box. No one is listening

This oil doesn't need any help being excellent, if Mobil thought the additive package on this oil needed moly they would have added it, much like they do on the vast majority of their synthetic oil lineup. They've intentionally omitted it from this formula and I doubt there's any way to make this oil "better"; it is one of their best.

Mobil uses 44 ppm Mo (and 113 ppm B) in my VOA of Delvac 1 LE 5W30. Evidently they do think molybdenum has a place in at least one of their premium truck oils.

Not only that, but they also use it in Mobil 1 0w-40, their flagship product
However, on this point I must agree with skyship, if this particular product needed moly, or if moly was advantageous to its performance, they would have included it. We KNOW they do in their other lubricants. SO this leads me to believe that by adding it ourselves, we would not be making this product "better" by playing "Chemist the home game".
