Here's a factory filter from the 1st oil change at 3,000 miles of a 2018 Mazda 3, 2.5L. I'm no expert at doing autopsies on oil filters so, you can be the judge. This was an early change to get the new engine particulate matter out. When the engine had 1500 miles, I put 2 oz of MoS2 in the oil and you can see it in suspension.
And yes... I have a pretty elaborate can opener.
