Anyone have any idea how well automotive oil filters work? Smallest particles removed, removal vs size, etc?
I've had a discussion recently which called into doubt the usefullness of oil filters as a whole - the idea being presented was that since the oil film thicknesses at various key locations in an engine are often less than 5 microns thick, and since most oil filters pass particles much larger than that, what's the point of having these filters at all?
I don't wholeheartedly believe that argument, but I'd like to hear some others' comments on the matter.
as always, thanks in advance.
here's an interesting article I found, which relates slightly to this discussion:
