Harry, I could not have said it better! High level oil filtration is one of the most important aspects of engine, or any fluid system, maximum life. How anyone could chince on this most important component is completely beyond me. But I see the same thinking in industry. I recently surveyed a large steel plant that uses water glycol as its hydraulic fluid (fire potential) and all of their inline filters were cellulose. Cellulose filters break down almost immediately when they see water anything. And in short order are not only NOT filters but contribute to system contamination. Yet the purchasing agent ruled that NO ONE was allowed to purchase any filter but these Vickers cellulose elements. (called cheap) Yet the filters were actually causing system failures and shutdowns..
It took a lot of writing and convincing but they saw the light and the poor purchasing agent saw the road....
Sorry for the long story but this story just completed itself last week with the plant replacing all of the cellulose elements with microglass elements..
So, it just isn't in the automotive section that the "stepping over dollars to save pennies" exists.
