It sound like you are in my friend's industry also. I don't even understand your post. All I know is that my friend's maintenance shop works closely with reps, including Cat. They analyze the heck out of used oil. They analyze the heck out of internal engine parts. And they apparently conclude that dirty air filters catch finer particles than clean filters do, while passing plenty of engine intake air volume. My friend reports that when filters are finally ready to actually be replaced, they are CAKED with dirt.
