They got me with those Black Friday deals... This thing should be arriving early next week! Still trying to get in a cross country trip before the year ends, so hopefully will be able to put about 7,500 miles on it in the next month or so.
Regarding magnets on oil filters
- Thread starter Hatsuwr
- Start date
I read the patent and it says the magnetic field is one way towards the pleated filter, there is no magnetic field detectable on the outside of the filter, very interesting.
I was looking at this thread wondering if anyone had actually seen the magnets on a filter attract any particles.
I was expecting to see cut open cans with a cloud of particles gathered around the magnets.
Has anyone seen the magnets actually do anything? Only the magnet experiment on the totaled Prius seems to have shown anything.

Yea there are a lot of pictures out there. Try searching with the term Filtermag, since those are relatively popular. Here are a couple of the first results I found:
I recently changed the oil on my '09 Vibe with a Toyota 2AZ-FE engine. I used the filtermag for around 1000 miles. The engine is still breaking in (around 2000 miles). I was amazed at the amount of fine ferrous dust that collected around the magnets. The oil was Mobil Clean 5000 5w-20 that replaced the factory fill at around 700 miles.
I used a pipe cutter to open up the filter. There was no dust created.

What's missing is an assessment of the particle size that was captured. If it's only particles that would be captured by the filter anyway, then the magnet isn't of much value. I'll hopefully be able to fill in some of that info in a few months!
And look at what a strong magnetic drain plug can catch. Yes, magnets catch a lot of ferrous particles too small for an oil filter to capture. Engine was still breaking in some. Half of the top is wiped away in the 2nd photo so the thickness of the layer can be seen.
Wow. What engine / application is this?
That was on my 2005 Tacoma 4.0L V6 after a 5K OCI from mileage 5K to 10K miles on the truck. That engine took awhile to fully break-in. Here's a shot of the magnetic drain plug with 50K miles on the truck.
Who makes a magnetic drain plug with that large of a magnet? Is that custom?
I’d like to try one if they are for sale.
I have a Votex on my K24 Accord that has a tiny little magnet. Seems to pick up a decent amount of iron particles, though. I’ll take a picture of it in a few weeks after a 10k mi OCI.
It was a custom plug by a small machine shop that sold them for a short time many years ago when I bought it - they called it "Super Plug". I just searched for them now, and can't be found anymore, so apparently not making them anymore.
However, look into the magnetic drain plug brand "Gold Plug" as they are basically the same. I have a Gold Plug brand magnetic drain plug in both my motorcycles and they pick up quite a bit of ferrous debris.
