Blackstone has at least two VOAs of TopTec 6600 0W-20. They should be able to compare your results to the VOAs to tell you how your results compare. This would provide you the most information as to how your results compared to brand new oil.
As a side note, what was your TBN at 7,500 miles on...
Thanks, I'll see what I can find on those forums.

The previous UOA was performed on the oil that was in the vehicle when I purchased it. It either has 1k or 6k miles on it, depending on when it was last changed. I posted that UOA here previously...
Sorry, I only included the relevant portions of the report initially but uploaded the full report now. The UOA was done by ALS.
I assume it was a 0W-20 oil since that is what the oil cap calls for.
I recently purchased a 2019 BMW X3 and had the oil analyzed that was already in the vehicle. Based on the CarFax, it appears the oil was last changed at the BMW dealer so it should be BMW TwinPower Turbo 0W-20 LL-17 FE+. However, the filter was not an OEM filter (still a Mahle filter, but not...
