But motor oils have so many additives in them today which trap the particulates, holding them in suspension then filtered out fairly well as long as the engine oil is at run temps the change intervals are greatly extended.
Bob regularly goes 25,000 miles between changes his engine has the equivalent of 1.8 million miles on it and has never had a bearing or piston and rings change done to it. However I had installed an OPS system on it when it only had 500,000 miles this 2 filter system in conjunction with the 2 primary filters and the centrifuge basically cleans the oil down to under 1 micron sized contaminants
