Jest? Surely? Science denier?
Science denier? Hardly. I've been involved with dozens of very large engines where bypass filtration is supported and recommended by the the OEM. This better filtration is part of an in depth program to extend base engine life. As mentioned by many here oil analysis with factory support as data is accumulated go hand in hand.
But and a very big but, the purpose of optimum oil filtration and analysis is to extend engine life not increase service intervals. For the 100 hour per year lazy boat owners, rarely changing your oil because you have a Gulf Coast filter is indeed bad science.
For those who enjoy using a search engine look up SOS for some interesting data on oil filtration. Further, Fleetguard has a good article on bypass filtration fact and fiction.
A few interesting side notes, cold starts are the hardest thing on engine moving parts. That is why gensets, commercial diesels in tugs, mining fleets etc get such long engine life. Second, oil filters break down over time and not only lose their filtering ability but release trapped particles into the oil flow. Thirdly, if you are seriously using an oil analysis program, an oil analysis on the clean oil is essential.
Don't take it from me though, or other anecdotal mutterings you read on the Internet. For oil and filter change intervals read what Cat, Cummins, Deere, northern Lights, MAN etc state in the books they give you. Many of these books are written for engines where bypass filtration is OEM with good filters.
Like the dentist, once per year or more often as hours increase prevents decay. Last but it least, you may be in for an eye opener when looking up costs for accurate techniques for measuring 5 micron particles and assaying same. It is a science well beyond a 50 buck quickie.
