Well that's an easy way of side stepping the question isn't it. Prove using the Fram ultra against another filter will produce less engine wear using the same oil. Prove the Fram actually make the oil cleaner, if it allows particles smaller than 20 microns then I would suggest it doesn't, just dirty oil with smaller particles. Will the FU, XP, Gold, OCOD, etc filter carbon black out? No it wont, so wheres the clean oil?
Which gets back to the question where do these particles come from? Years ago when PCV systems used a small fiber screen (not really a filter) in the air filter housing on top of the carb pre filter no less then that was an open avenue for particle ingress and a more efficient oil filter may have been of some benefit, those systems are not common today.
Another point you fail to address is the simple fact that for a filter to do its job the particle regardless of size has to get from the sump to the filter, that is undeniable.
It has to go through the oil pump first and that is an area for wear that can have significant consequences as commonly found in old Buick engines. The pump would wear and the engine experienced reduced oil pressure over an extended period of time until it was low the oil pressure sender would trip.
The fact is this reduction in pressure and flow contributed to engine wear a lot more than a few particles. If you had a mechanical gauge and were aware swapping the front aluminum cover which included the pump housing and pump before that you could save the engine.
Forget the test using controlled test with specific sized particles introduced into oil, that is just bogus.
The simple premise that better filtration will result in cleaner oil and thus reduced engine is a false assessment. The example I just provided proves it and anyone that has ever owned an old Buick and had the issue of a worn pump will confirm it as it was well known.
