i will be performing a test here real soon for all the non-believers (me included). this thing is supposedly pretty good and my buddy Dan in the shop next door runs em on is Duramax. 4Wheel magazine just published some test results of there own. A guy used a super high powered magnet vs. the filtermag and the Filtermag won. A normal magnet will not hold any Micron count due to the rushing and flowing oil passing by. But this filtermag is almost imposible to pry off, (over 600lbs pulling power) and once you do you can use a can opener like device (so no cutting debris gets in) so you can actually see reults. Oil filters are rated for what 40 microns or so? this is supposed to trap a percentage of up to 2 microns... doubtful but it looks like it will help. Any amount of abbrassive material removed from my engine oil is worth a couple bucks to me. Any thoughts? i just ordered a couple so I can hack em up and test em out.

 

Interesting!

Keep the results posted. I would like to learn more!

Thanks!

 

I'd rather use an Amsoil bypass filter if I wanted to filter down to 2 microns.

 

Interesting website they have. Some of their claims are a stretch at best but the real meat is in the oil analysis they have posted. Using a by-pass system only, the iron wear metals are around 3.7 ppms per thousand miles. Using their magnets, the same iron wear metals went to 6 ppms per thousand. Wear went up amost double using their magnets. I'll be first in line to say that doesn't make any sense and the test results are flawed. They also post a ferrography test but the by-pass filter , if it's worth anything at all, will catch particulates to 3 microns. I've never tested one of these newer magnets but have read reports stating both ways the actual advantages of using them. It's probably helpful for an engine that doesn't see regular maintenance but for a maintained engine the benefits would be small, if any. Back in the 60's we had a magnetic drain plug that was popular and I had one on my 348. I never found anything on mine but oil.

Normal oil filters of today will filter similiar to the Purolator. That filter is rated at 10 microns- 95%- single pass. Some of the high flow filters will be at 20 microns-80%- multipass. A 40 micron particulate is large enough to cause damage to the engine. A micron is 1/1,000,000 of a meter. With todays cleaner burning engines and that the sealants used negates any outside debris from entering the engine, you don't have the issues like we had back in the 90's with floating particulates in the oil. I don't see the need for these gadgets but if you are inclined, you certainly won't hurt anything by using them.

Note: Its a little outdated... but still a good source of info.
Labnerd: I also don't see much need for em, and I am pretty doubtful of any benefits... but 600lbs pulling power?? I figured I'd at least give it a try. And I am trying to get this damn page to scan so I can show you an un-biased test reult with these magnets on. He put it on a small block chevy (running in his Jeep) at 28,000 miles. he then did the oil change at 30,000 and began using th can opener method, limiting the debris falling down. The pictures of it are pretty substantial. nothing to drop a jaw over... but sounds like it'll help. Liek you said... perhaps on longer service intervals for some customers?? The Puroltaor is rated at 10 microns? i had no idea... but if true, I may go out and buy one. Like I said... to me it sound about as helpful as the Throttle body plates ("Tornado"). I dunno... but should be a fun experiment.

 

What have you found? Does it work?

 

whoa ! post from the dead.

Never did run it. Everyone I kept talking to chalked it up to snake oil magic. Sorry.

 

I was just reading an old article from "Off-Road.com" about how great it was suppose to be.
