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.
