Posting up the report I just got back from Blackstone a few days ago after my 65k change. Slightly longer interval than the first sample, but the Liqui Moly Molygen 5W-40 seems to be holding up well according to their comments.

Thank you i noticed after i changed and did a few samples that the engine was doing pretty well, at least from the reports.
The most important characteristics though i think are with the viscosity ratings. when i was using the Liquimoly 5w-40 and 5-30 oils the oil was never the right viscosity rating when at temperature, and i feel like that is what most of the wear is occuring really. if the oil is shearing and not being protective at high temperature and medium loads, image how damaging a high heat, high load situation would do to bearing materials and other internal components.
On your report the engine looks to be doing well, but consider trying a -50 weight to up the viscosity at temperature, and you should see less wear in the engine. either liqui moly 5w-50 or redline right now seem to be doing the best on these engines for the high heat load present on the oil.
