Oil Filter Magnet Question

[ZZman]

I got 3 Klear Force Oil filter magnets for Christmas (thanks Santa!) I have put them on my 3 cars. My question is:

Do you think the first oil filter will have the most metal particles being this was the first use and metal particles has been building up inside the engine? Should this them go way down on additional uses?

Yes

Not a lot of metals in your engine is magnetic, only Iron and some other metals which aren't common. So I would say no. I bought a Filter-Mag and used it on my car for 5K then cut open the filter of that run and the next run. I didn't notice any more or less inside the filter. There was a bit of magnetic residue inside, but not enough to clog a filter.

Think about this:

In an engine, the two main WEAR points are the bores and the rings. These are both ferrous

Are Ferrous metals magnetic.

Ferrous metals are magnetic. If you have enough Ferrous metals to clog a filter sell the car.

I totally agree.

DEFINITELY. But of course the potential here is that if you use a filter that is efficient down to 10-microns, the magnet could catch the even smaller particles!

I read that the big wear particles are 2-20 microns. So even a 10 micron filter would not catch alot of them.

Since Iron wear is the most common in UOA's and it is magnetic, I see the sense of trying the magnets.

Exactly.

Combine that with the fact that the only filters that are efficient at 10-microns are those spec'd for diesels and.....

Yup, I see magnets being potentially beneficial. At least in theory.
