Anyone else do this?

I put magnets from a hard drive on the bottom of my oil filter and drain plug.

You can buy drain plugs with magnetic tips..i have one, i know you can buy oil filter magnets, i dont think they help too much.. the oil pressure in the engine is at 20-60psi, not sure a magnet around the filter can hold metal dust at that pressure.

Just because the gauge reads 20-60 psi doesn't mean there is 20-60 psi on the drain plug or on the pan. Magnetic drain plugs are used by many oems and have in my experience worked well. Pep Boys sells a magnetic 1/2"-20 magnetic plug for $2.49.

IMO a magnetic drain plug is worth every penny. I used to manage a couple quick lubes and those magnets do work very well as does the magnets inside the tranny pans of most cars. I've seen some crazy shavings come out of some peoples motors and trans'.

if you read my post i never said there was 20-60psi on the drain plug.i know the magnetic drain plugs work...there is 20-60 psi on the oil filter however......

I use magnetic drain plugs for years in all applications that I can Magnetic Oil Drain Plug for LT1: Motor Mite 65203

I'm doing this exact same thing. That damn magnet must have about 75 lbs of pull on it. I'm sure no particles are being pulled off it.

Been running a filter mag ever since I've owned my car along w/ the mag drain plug. For those who say they don't do much buy one that has 575lbs of magnetic force and cut the filter open afterwards. You'll wish you've had one all along. 60PSI doesn't stand a chance.

S.J.S.

Where do you get one of those 575lbers for the filter?

ZBLKHELLRZR

Filtermag.com sells 2 versions. One is 265 or 300 and then the other is 575lb or so. But that magnet will cost you 100 bucks. Yeah it's expensive but it's cheap insurance to me when it's runnin on my stroker.

If you guys are saying magnets are so important (which they are) you must be finding a significant amount of metal. If it was me I'd be worried about how that metal got there in the first place because that's ovbiously going to cause some kind of problem, magnet or not.

I had a ceramic speaker magnet on the oil filter on my old Catalina and a magnetic drain plug. There was always magnetic "dust" inside the filter (which is before the oil is filtered-outside to inside) and on the magnetic plug in the pan which is post filter. I figure that is two sets of particles that weren't going through my bearings. That couldn't be anything but good.

I guess I should say that i put Neodynium button magnets on the gas filter too and it catches particles as well.

I with you on this one. I have the magnet on my drain plug and I ever see metal shaving on that, then I will be getting worried.

The accumulation is more like a fine powder. There will always be iron in your oil from normal wear-you will never escape that. I've run oil analysis on my cars with magnetic drainplugs that get metal on the magnet and the tests have all come back good-so nothing is wrong. It's also a cheap way of noticing any excessive wear, but oil analysis can usually detect problems before they become any significant damage is done. I'd rather not have iron floating around in my oil if I don't have to.
