Either you misunderstood my question OR I didn't word it properly.
I'm aware of the type of test you're referring to as I've taken several basic courses on how to interpret oil sample reports that are obtained from an analysis lab. I've got a fair understanding of what Beta ratings and ISO oil cleanliness ratings are.
I understand, that as an engineer, you performed labratory tests that determined the efficiency of a given filter BUT what I actually wanted to know was whether you'd done any testing to confirm the results of using filters from different manufacturers on actual components such as engines, transmissions, gear-boxes, hyd. systems, etc., regardless whether it is expensive or not............
Only a fool would deny that internal wear would be the same between components using good quality oil and filters VS components using poor quality oil and filters BUT a wise man will ask how much difference is there and PROVE IT! For example, he will want know if using filter brand A will get one of his trucks to 40,000 hrs. before an overhaul compared to using brand B which will only get him to 20,000 hrs...............Having that answer and proof, he'll then be more likely to part with the extra dollars to buy the brand A filter instead of the cheaper priced, brand B..............

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule.
