Mobil 1 filter on a 2014 Fusion with a 2.5. About 6,000 miles on Syn oil. Double Filter Mags on filter

Looks good.
Thanks for sharing. I would have expected to see a lot more ferrous material on the inside of the filter wall. This is surprising to me. I guess that is a good thing, in a way.
Do you have a magnetic drain plug also?

One should not expect to see a lot of iron particles coming out of motor oil. There's very little steel-on-steel contact in an engine.
My only question is whether the filter would have caught those particles anyway. Since they are on the outside, where filtering actually begins.
Oil pan magnets kinda make more sense to me, since once iron particles settle there, it's not entirely likely that they will be picked back up and filtered later.

that's an accessory /I didn’t know the Mobile One filter contained magnets; learn something new every day!

No drain magnet. 2014 Car only has 45,000 miles on it.
That is news to me. Whats with camshafts and valve train, cam chain wear is a very common source of metal particles.
I guess that would depend on particle size.
Yep. It would be more interesting if we could separate out the bits that are smaller than 25 microns or whatever the absolute minimum size the media is rated to.
Motorhomes, boats and air cooled gensets being an exception,
The magnet does that very well.
I agree. However I can think of a few steel parts. Camshafts, crankshafts, rings, cam followers, roller bearings, and timing chains. Prob more.
lifters, oil pumps, sprockets....The DI pump exerts nearly diesel level pressure on the cam
I use "Gold Plug" drain plug magnets. Might be worth it to you for the Avalon if you care too. The "Gold Plug magnet is so strong its almsot retarded, if your oil pan is steel sometimes you have to hold it firmly or it will attach to the oil pain as you try to put it back in.
I kind of believe in the magnets (either type) hey, it's a way to take iron or any metallic metal out of the oil so why not?
Its well known oil filters only are efficient down to a certain micron and even then it's a matter of who catches the particles first. Dont forget during start up and acceleration most oil isnt being filtered, its going through the bypass valve. Even if these particles are too small to do damage, in a forum where we all look to do as much as we can for our engines its certainly a cost effective, reusable way to do it.
Yep ... pretty much everything but journal bearings.
Once the oil is fully warmed up, the chances of the oil filter hitting bypass is very rare. Maybe if the filter is very clogged it might, but in that case the maintenance is being neglected IMO.
Yes, exactly and a magnet will help filter the oil while the filter can not, heck, some winter areas and short trips oil may not ever warm it up enough at times. Unlike water temperature it takes a long time for oil to reach full operating temperature.
