Can magnets keep oil cleaner?

Rare earth magnets are amazingly strong. I've attached a disc shaped one to the exterior bottom of my oil filter, thinking at least some of the magnetic force would pass through the filter and perhaps catch and hold iron-based particulates.

Has anyone had any success with this concept? Further, has anyone droped their oil pan and inserted a REM in the bottom for the same purpose? I would imagine you could leave one there for many thousands of miles before having to clean it. What would be the best shape of a REM for this purpose - one that lays flat in the bottom of the pan, or a cylindrical shape that sits up a bit?

Would all the magnetic engineers please chime in...
 
I have not used any magnets on my filters or pans. However, I have always used magnetic drain plugs. They seem to consistently attract and retain a small amount of material. So magnets do work, well, at least the drain plug equipped ones.
 
how about the ones that you slip inside the filter, is that any less or more affective than in the drain plug?
 
Those magnetic balls that you drop inside the center tube surely snag something, but that's the last place I'd want the accumulation of metal ..on the engine side of the filter media :shrug:

I don't know how long it would last with heat and stuff, but just wrap a coil of wire around your whole filter and run DC through it. The whole thing magnetized.

I took a velcro strap and cut strips in the material, placed dime size magnets every couple of inches. The strap just wraps around the filter. I felt the strap should go about half way between the top and bottom of the filter. To close to the bottom and those strong magnets could move that spring. It has been on for close to a year, I will remove and disect this Spring. Also, I have been running the Amsoil bypass for minds sake.
 
Adding high grade Neodymium magnets to the outside of an oil filter is a total win/win situation. Magnets filter from 1 angstrom on up through chunks and clunks AND reduce the oil filter loading..
Never, ever put a magnet AFTER a filter. Magnets can create ferrous clumping and a clump may break off, going directly to the oil pump, bearings, etc... thus nothing in the center tube. Oil filter external surface only.

You should check out filtermag.com. This might be the product you're reffering to. I'm not pushing their product by any means, but they information they have is pretty interesting. They use "high powered" magnets outside of the oil filter and transmission pan to trap the metal particles that the filter missed.

VERY COOL
 
So I harvested a couple of these from a defunct 30 GB HD of mine. Let me tell you, they are very, very strong magnets indeed (the neodymium ones). It's the first time I've really had a look in side of a hard drive. Pretty cool indeed.

Should I just stick the two of them any where on the outside of the oil filter?

I think our recently departed board owner, Tony, used one. I haven't heard of too many others using it. I'm sure it does a fine job. The difficult thing is that most of us probably want to see the accumulations ..which I don't think you can with the forcefield insert.
 
its funny today i just changed all the fluids in my new "used" car. when i drained and fills the front and rear differentials, they had a magnetic drain plug & there was alot of greyish goo on both of them. the car has 43000 miles and i bet this oil was OEM. so i guess magnetic plug do what they were designed too?

I always put one on the drain plug. Almost every oil change, I'd find some goop on it...except on my Subaru engines. They are CLEAN!

Probably indicative of the Subaru engines which do very well with UOAs despite the various oil used.
 
Leo, yep, I think the Subaru engine might be one of the best wearing engines on the market. They have some other problems that surface at times, but, generally, wear is minimal.

arkainzeye, I ALWAYS see fuzz on differential drain plugs...no matter what application. But, that's only about 25 different vehicles, so, that doesn't make me an expert!
 
i installed magnetic drain plugs (from the dreaded pep boys) in all 3 vehicles...no oil changes yet to see what they found!
