Wouldn't a particle count(PC) on the oil and soot/insol % comparisons via UOA(trending already established with other oil filters) help to determine how well an oil filter is working in any particle app?

Do you really believe that car had a history of 6K OCI's with the oil level kept full? I don't. Nor do I buy a 3-4K limit on any modern oil filter in a clean, correctly functioning engine.
Can't saw how much of that thread is true or not ... but point was that filter manufacture's have the "3K miles or 3 month" OCI CYA mentality for car owners with sludged up engines such as the guy in the thread.
I agree 100% that with a clean engine an oil filter can go much longer ... most could probably go 10K miles with no problems.
+1 The 3k recommendation would be for engines of unknown maintenance history (in link) and/or unknown recommended oil change interval.
Do I really believe the linked car/filter had a history of 6k OCI's? Heck no. As I said on that thread, we don't know, the rest of the story.
As said, the P1's 13 grams rating is a bunch of junk, and would easily cover/handle a well maintained vehicle in a 1 year 7-10k OCI.

Ran into the thread again and thought it deserved a bump for those that missed the pics. great pics for the age old question of D+ vs P1
For anybody new to the oil filter forum, I think ZeeOSix and sayjac are two of the most knowledgeable guys on BITOG. He's not in this thread, but river_rat is excellent, too.

p.s. I am sure the particle size is intentionally hidden because of >> 20 microns.
