Unless the engine is cold/oil too thick, the total oil flow is through the filter. Placing a magnet somewhere must only affect some of the content of the oil flow so it must be haphazard at best. A back handed appeal to authority I know but the fact that manufacturers are not including magnets in oil filters or, generally, in oil systems seems to indicate that the value of magnets might be suspect. I don't see the potential for harm, so long as the magnet cannot move into interference areas, so like a magnetic drain plug or add one to the outside of spin on filters but that isn't because I can support the benefit. Placing a magnet into the oil flow may simply result in small particles, which one assumes to be the main material which a magnet might remove, being flushed from the magnet by the oil flow. The smaller is a particle, the larger the surface area in comparison with its mass. Since magnetic attraction is relative to the mass, smaller stuff is easier to flush off. I'm not asserting that this is impractical, simply stating that I don't accept the argument as presented. Were I to place a magnet into the oil filter cavity, I would wish it to be secured so that it cannot move around and possibly cause damage/puncture of the filter media. It would also be needful for it to be easily cleaned. I agree that it should be placed in an area where it will affect as much oil as practical but don't know how to quantify the effects of oil flushing material from the magnet. Anything over about 25 microns should be caught by the oil filter and this includes all types of materials. The magnet, at best, will only capture a small portion of magnetic material while the filter should capture materials of any composition. One benefit might be for people who insist on using oil of too thick base weight which causes the filter bypass valve to remain open for more time than is intended. One issue is that basic physics shows that magnetic attraction decreases as a square of the distance so the effect becomes immediately so weak as to be insignificant, especially given the viscosity of the oil and time in which the magnet has to act on materials in proximity. Very high strength magnets such as high powered electromagnets acting on stationary oil might have significant effect but one must question other conditions. Some of the material cleaned from magnetic drain plugs is clearly not magnetic (wash it off, then try to pick up all of the material by using a magnet over the settled material) which leads me to conclude that much of the material has simply settled onto and into the irregular "stuff" on the magnet. Interesting subject but one which seems to lack data to support the use of magnets. "Seems" to me perhaps because I understand so little about the effects and conditions. All this is fun to think about. I know there's research being done to test whether dumping iron particles into spilled oil, then using magnets to retrieve the oil but that's a completely different...opposite effect than what we are considering. Interesting though. ------ Original Message ------ From: "mark ward" To: "DSN_KLR650@yahoogroups.com" DSN_KLR650@yahoogroups.com>; "Norm Keller" Sent: 2014-10-31 12:10:53 PM Subject: Re: [DSN_KLR650] Re: Motion Pro Oil Filter Magnet
I would say YES! Based on the Drain plug Mag, collecting metal "dust". The faster it takes it out of the oil cycling threw the Engine & Clutch plates ETC ETC. the better. Where? (What end?) 1st thought. Closest to the engine side, where the 1st side hole in the tube dumps oil into the filter, BEFORE Leaving the filter.

It amuses me to think that it might help something and costs nothing. I just snap the magnet to the end of the filter and switch to the next during the oil change. It's likely the same for those Motion Pro magnets. I'd expect to see magnets included into oil filters if there were a demonstrable advantage though so simply amuse myself thinking that it can do no harm. What if it magnetizes the liquid tungsten and generates eddy currents making my crankcase vent glow in the dark?Sorry, was thinking of those woo products which use magnets to "orient the molecules of the fuel" so improve mileage and other fantastic claims.
Cleaning the goo off a drain plug or oil filter cavity magnet adds to the tactile experience but couldn't begin to construct an argument to defend that these magnets actually are useful. I suppose we could do a survey here in which we use a magnet on alternate oil changes and compare the oil analysis reports? Might be fun and would be interesting to learn the reported outcomes. Not certain that the study model would provide the data expected but willing to opt in if we had 20 or so others who would do so for, say... four oil changes. That would be two with magnet & two without. Time of year/temperatures, oil types and riding conditions would have an effect so summer might provide more consistent conditions.
