Noticing the posts regarding oil filters and such I have been using a FilterMag http://www.filtermag.com on my coach since I have had it (about 10 years now). Steve Ferguson turned me on to them. Since then I have have made a point of cutting open my filters after each oil change. (Mobil 1 Full Synthetic).
Every time, I find a layer of grey “dust” clinging to the inside of the filter case. This is obviously cast iron from the block which is a ferro-magnetic, material from the rings and hopefully other stuff that is not the crank. The FilterMag seems to trap it. It can’t be good having this stuff which is extremely fine going through the motor. I’m not sure if the filter is catching it all. This may be one of those scam things like the carburetor “vortex generator” but I think it actually does help in keeping the ferrous metals out of the system.
Summit Racing sells both the FilterMags and oil filter cutters. I think Jim K also has FilterMags.

I have been using the FilterMag since 2002 on both of the coaches we have owned. Dick Paterson of Springfield Performance Ignition suggested and sold them at the GMCMI conventions. I agree with Gary on the value of using the unit.

Filters capture larger particulets above 5 microns.
Like to think the magnet will collect smaller ones.

I use a magnetic drain plug but this is probably a little better.

When we went to the PACCAR CENTER IN LA CONNOR, Wa, they had a diesel
engine on the test fixture for durability testing. It ran under varying
load and at various speed to simulate real world conditions. They changed
engine oil at 60,000 mile intervals. Engine expected life, 1 million miles.
The oil filtration system removed 5 micron and larger particles. It used a
combination of paper filters and centrifugal separators. The engineer I
spoke with remarked that there was no need to remove particles smaller than
5 microns. They had more concerns with combustion by-products, particularly
acids. Their separators removed them, and saved samples for analysis.
Cutting edge stuff. PACCAR is a European company that owns Kenworth Trucks,
and manufactures diesel engines in Europe. Could have spent a week there,
but they only have open house one day per year.

I find a magnetic smudge when I wipe my drain plug magnet. My micron converter gives 0.0005" a 12.5 micron.
5 micron is pretty good protection; but it may take several passes through the media to get to that level of
protection. My feeling is to keep the airborne grit out of the engine. Silica in the oil analysis is your
tell tale.
