This wouldn’t have had happen if he used that new Fram Endurance filter.
16,106mi M1-212A failure C&P

I think the problem is with the high bypass in cold climates, perhaps because the bypass activation pressure is so high it causes a rapid drop in differential pressure, shuts again cause a rapid spike in pressure on the inlet side again, which rapidly opens the bypass but then it bleeds pressure quickly and shuts and then the cycle repeats and the repeated compressions and decompression are ripping the media apart.
Combined with that stellar Puro media & pleat spacing, it's a miracle they last 5-7500 miles.
Media has some grit in the bottom of the pleats but I wouldn't say its excessive
Time for a better filter. Nice photos. Thank You
What company manufactures that filter?
That's a different media tearing failure, in that the media tore down deep in the pleats, and on pleats that didn't have any wide spacing - so the media didn't tear from the pleats excessively bending. Leads me to think (like others already mentioned) that this filter was seeing repeated high bypass valve dP across the media - Note, the max dP across the media is way less than the max oil pressure seen on the dashboard. The dP is at or maybe lightly above the filter's bypass valve setting. Could be where the media tore, the pleats were not fully contacting the center tube and with repeated high dP events they finally tore open.

Please explain what is wrong with Mobil engine oils? Please explain and provide facts.
The filter tore. It should handle 10k. I pushed a ancient tough guard to 20k plus before.
This was my thinking as well. I've pulled oil filters off equipment that were in use for a decade, and the media stood up to the abuse.
The owner has taken uoa which has brought him to 16k interval. I collected sample for him and he can decide with uoa what interval he wants to use next.
Thank you everyone for the helpful feedback. I am less concerned of the engine having a mechanical problem and will likely switch out the current m1 212A for a wire backed titanium or endurance at some point this interval, even though this interval wont likely have cold outside temps and higher media dP. I will post the uoa from this oil interval if possible.
Note that the Titaniums are switching over to non-wire backed media, as the Ultras did. Bring a good flashlight and verify if it has wire backing through the center tube.
This would be a good test for the Supertech MP that claims 20k miles.
Explain to me how their oil is a joke?, I hope a certain youtuber didn't get in your head.

Mobil doesn't make oil filters, they are produced by the same pair of companies that produce all the other filters. We've seen tears on many filters from across the spectrum, the only filters we've never seen tears with are the synthetic media ones like the OG Ultra, EaO, RP...etc.
This isn't on Mobil (and their oils are just fine, that assertion is baseless tripe) it's on who manufactured it, though Mobil may or may not be who handles the warranty depending on how the arrangement works.
I think I would dial back the OCI to the recommended interval, or maybe 7500 miles max and go for a wire-backed filter like the Fram Endurance, then if all looked well at the next change gradually increase to get back up to 15K or so.
A UOA will show if the oil change interval needs to be changed, but regardless the filter is the issue here, not any of the other factors. There is a post a few lines up from this one currently of a cheap Champ WP2835 that took 16,000 miles of abuse and looked much better.
Obviously a wire-backed filter would be a better solution, but they are more expensive.

But that's a filter with the standard ~8-14psi bypass not the ~16-28psi used on newer GM engines. A PH10063 or PH10064 used is a cold climate is a better comparison.
