Oil Filter Magnet

I personally think its a great Idea. Racers have been using it for years. I use several on my race motor. Drain plug, one on the oil pan rail and there is one in the magnus reusable filter.
Anything to keep the oil clean of C R A P is a good thing.

so you would prefer to let iron damage the engine and know the engine is being worm by iron ?I would rater add magnet where needed like 1 or two in the head area one at filter ,since the plug is magnetized no problem in the oil pan area
The only reason I am using a filtermag is because it was given to me for free. I have never done anything to analyze its effects, but I don't believe it can have any negative effects.
I, too, wonder if all the stuff magnets catch would be simply be removed by the oil filter.

Another method is to simply get a button magnet from a science lab supply store (on the web) that is just small enough to be pushed into the drain plug, letting it drop into the oil pan. Add one every two years, leave them in.
My cars have aluminum oil pans, so they would roll around in there. The oil pump screen and filter would keep it from being ingested. One hopes they would not all stick to the pickup screen mesh, maybe best not to put more than one or two in there.

Oil filters let anything less than around 40 microns or so pass, so particles of iron that size could only get caught on a magnet, maybe a drain plug magnet. Since oil film thicknesses in the engine vary between zero and 100 microns, particles 40 microns or less can dig micro-trenches in internal metal.

When I drain the oil I take the magnet off so most of the sludge is swept away with the draining oil.
By placing a magnet on the oil pan, wouldn't the oil pan become magnetized? And with the pan magnetized, won't at least some of the metal particles stay in the oil pan?

You would need a very large magnet to achieve that. The oil pan has a lot of material to it.

Same, being in IT has its perks.

You don't think automotive engineers have defined the filtration parameters to protect the engines they design?
And you think some bozo selling oil filter magnets knows the "truth"?
Throw the JC Whitney catalog in the trash can before you buy the toilet paper oil filter conversion too.

I use very strong Neodymium magnets on all our autos that have spin on oil filters.
My thinking is-->They dang sure will not harm anything. They can only benefit. It has been shown-->They do the job they are put there to do.

I was going to stay out of this discussion as Jim Allen pretty much answers the question with science.
Our Chief Engineer says that magnets will not stop/catch anything that a quality filter wouldnt have caught anyway.
That said, your statement about 40 micron particle size is incorrect. FRAM filters are between 95.7 and 99%+ efficient at all particle sizes 20 microns and larger.

ty motorking ,so if user wanted the same benefit as some trucking filter the only solution is?bypass filter?

I learned of the product in this forum, actually.

There are probably plenty of ferrous particles below 20 microns that get through an oil filter at some point. Some of them might be caught along the way, but lots get through and that is where a good magnet comes in. Some wear studies say that particles below 25 microns can do a lot of wear.
Here's a couple studies that are interesting.

Yep, that's why bypass filters were invented - to filter down to like 3 microns. That's because particles below 25 microns can also do damage. See Link #1 in my post above.

Fram filters are very efficient at >20microns as you say (ISO 4548-12), yet some other cheap cellulose-only media filters let a lot of stuff pass above 20 microns.
Still, I think Jim Allen can appreciate that iron particles smaller than 20 microns could get caught on a magnetic drain plug or filter mag.
