From a lube engineer's perspective, there are limits of filtration of engine oil. Anything below 6 microns and we can begin filtering viscosity improver.. i.e. there is a happy medium. Moreover, all indications are that this filter is world's better than a paper element, both in flow and capacities. And yes, it may well last to 60,000 miles in its present form and very likely even in a tighter version, same performance. I realize it sounds strange but the performance difference between a microglass and paper is normally just that. I have seen a 30 micron Beta 200 paper element need replacement at 30 days, yet its 6 micron beta 200 microglass element needing replaced at 120 days.
The microglass element was filtering to a much tighter tolerance yet lasted 3 times longer. As much as 40% of a paper element may not flow oil at all! A microglass element flows 100%, which is why they flow with so much lower Delta P. (measured flow resistance)
So, from my experience, there is just so low one can go, micron-wise, in a full flow oil filter. It has been shown that the 10 to 30 micron particle size is THE culprit for wear, so if the EAO attacks that size component with good efficiency, we have a winner in my opinion.
You can well see what my particle counts show for the OEM paper... Hopefully this will be significantly reduced in the next go-round.
