Thanks for getting such comprehensive testing done and sharing.

You are welcome of course.
My intent for the PC was to see if a high efficiency filter made any real difference in real world PC and possibly if PC increased or decreased over time. The TAN raised concerns and I wasn't prepared to risk my originally panned 20,000 mile run so the data isn't as comprehensive as I had hoped.
I did put the HAMP "shortie" on it which should be about the least efficient filter available (tiny with no end cap design) and I will pull a sample at the next 12,000 miles and get a PC to see if its better, worse or the same.
It won't - in my opinion - really prove anything, but if more people would do something similar it might generate enough data to form a hypothesis...
I will likely not continue with this oil (unless it gets within a few bucks of EP) past the sump currently in the car, since my usage model doesn't rack up 20,000 in a year.
