You have also criticized other companies for producing unsatisfactory products. Is STP not a "well known Maker" or do you think its possible that companies produce things that make them money regardless of how well they sell?

I've combed through your old threads and found nothing of the sort.
Furthermore, what in the world does "abnormal silica" in the oil have to do with air filters?
Here you go. Seems they said the exact same thing I did.

To add to the discussion why don't we bring in the HVAC washable filters that exist? They have better documentation and have to pass a different set of standards than any crap you might put in your engine bay.
I really liked this line.

With the various makes of Mercedes Oil Filters I cut up some of them myself and took a look. I also wrote to some of the makers and found that they have no idea what the bypass section of the Oil filter filter down to.
I also viewed the extensive evidence from many of our members. So my opinions on the Oil filters is backed by personal observation, some evidence I found out and other evidence from our members. There is 3 extensive threads on the issue. I speculated on nothing.
Anything involving oiled air filters of the cotton type like the K&N nor any foam types (which I have no experience with) has zero to do with the washable Frams that I am using on my Vehicles.
When I did use the K&N Filter I used it because I had blow-by contaminating and wrecking the disposable elements. Since the K&N is oil impregnated a little Oil vapor does not harm it.
With the extensive arguments I faced for using the K&N I can personally say that I never could feel any grit on the inside of the hosing which would have stuck to the blow by oil.
Then there was the report from one of the Members that said he worked in a Shop that did extensive work on Sand Buggy Engines. He said he never saw any evidence taking apart Engines that the K&N filters were not working.
Also the K&N air filters are oil impregnated not oil coated. The oil absorbs into the passages in the fabric. The fabric crates may labyrinths that the particles have to negotiate and the particles impact on the oil and stick.
The answer to the other issue you provided yourself: "Generally, high-performance dry filters can
catch up to 99% of the incoming contaminants due to the smaller micron size of the filter media,
while oiled filters catch about 98% of what passes through – a minute difference, but a difference none-the-less."
As you said "not a big difference." And it is entirely possible that disposable elements from different companies perform differently; some my perform better and others worse.
In you case you are unable to answer if the unoiled Fram washable air filters have poorer filtration.
