Millions of times? Are you saying that the particles that are never captured by any filter (0.0000% efficiency) are the ones that do this polishing wear? All filters are going to capture particles down to a low level, but just at a low efficiency. My window sceeen at home traps 2 micron particles, just not very efficiently. The same is true for an oil filter per the graphs that were posted. I donít see how all these damaging particles go through the filter 100 times much less a million.
When I cut open a spin-on filter that has 2 FilterMags on it, rinse with varsol to remove the oil and leave the caught metals,
it sure looks like the filter media doesn't do a heck of a lot. Does it catch some? yeah, just not much, what's left could polish
and wear as per the question in the first post.
When a ran a guesstimate in my case, miles, ave speed, engine hours and GPM likely from the oil pump I came up with 400,000 passes
of the oil thru the filter.
Oil filter makers in research papers say a particle can be caught, but also may be released later in actual use
and caught again, maybe.... the vast majority of particles under 10 microns will easily go thru 100 times +++ easy.
Even on my old cars, never had a filter where there was significant solids piled against the pleats of the filter.
Yeah, there will be 1 in a million engine and filter that does, but not mine yet.
