Oil filter/magnet-revisited

[Whitmore]

Was reading Fire Chief mag and ran across a good article on oil and microns,the Bear Trap company says that in there testing that their magnetic filter wrap will reduce the number of 5 micron particles of steel,chrome and iorn by 80% with similar results with larger particles.
I under stand their consept and I have a magnet that I will put on my oil filter and help grab these unwanted particles out,my question is what micron is our filters good down to? Kevin

Re posted from the thread pointed to above - this subject REALLY interests me due to the installation of a Frantz bypass filter on my '91 Dodge/Cummins, and the subsequent oil analysis I had done a few weeks back...

UNFORTUNATELY, what NONE of the above info addresses, is what PERCENTAGES of standard "wear particles" fall into various size categories! In "standard" engine wear, are MOST particles in the sub- 1 micron range, or larger? *I* have yet to obtain ANY clear definition of the size span of wear particles, and it seems pretty clear to ME that if only 5% (for example) of actual wear particles fall below 1 micron, getting all excited about filtering them out is pretty much a waste of time and money!
ON the OTHER hand, if *70%* of wear particles fall into the sub-1 micron size, THEN greater filtration of those sizes DOES seem beneficial. UNTIL someone comes up with general specs on PERCENTAGES of various sizes of wear particles generated by our engines, tossing around various particles sizes is rather vague and meaningless - other than as used for advertising hype by various filter salesmen! #ad

Another case in point is oil analysis of wear particles, and the effect of bypass filtration upon the reliability of such analysis IF the bypass filters slew the readings of Iron and other cantiminants due to filtering out those traces, rendering analysis flawed as to ACTUAL wear taking place - causing owners to THINK there's not much wear when there actually IS, it's just being trapped by the bypass filter and not being revealed by oil analysis! #ad


Tell me, SHOW me, the actual percentage SPREAD of various sized wear particles generated in a normal Cummins diesel, THEN we can actually GET somewhere! Until then tossing around random particles sizes is just a meaningless numbers game to impress the gullible and unwary! #ad
