Cummins announced the 3 millionth 6.7 sold to Ram/FCA this year. 3 million times $10 is a lot of money. If the magnets don’t help, why are they in the transmission sump and in the differentials ? Got a magnetic plug for mine and it’s going in next oil change.

Fumato valve on pan, magnets where you want either on pan, filter, or both. I use silver perm marker that i marked around magnet on pan so i put it back in same spot just in case there are any shavings that exist that didn't flush out when oil was drained from pan. No more wrenching on/off plug, no more leaking plug gasket/seal, any metal is captured in one of two places if it exists. I don't know of any other ways to capture metal stuff other than adding a centrifuge secondary oil solution for the really small sludge stuff. But that's really a solution that focuses primarily on other crap in oil that your filter can't get - different discussion really. Open to other suggestions as I'm sure there's probably something to learn here as I always do.

There is a lot of movement of oil in the filter.

Exactly. Imo that is why It would a good place to attach an oil filter magnet.

The other thing that was mentioned about the oil sludge being at the bottom of the oil pan and not all of it coming out when drained ... well, I would think regular oci's and a good quality synthetic oil would reduce that from happening.

No that movement removes the iron from the magnet. Look at the oil pressure in the oil filter vs the oil pan.

Sludge in oil pan - means greater problems then a few iron pieces in the oil.

You are very foolish

You are funny.. I drove OTR for years, the engine in one of the truck I drove never had a magnetic drain plug, at 400K on that engine they decide to pull the pan to check the bottom end, they just rolled in new rod & main bearing while it was open, that engine then went another 300K before a ring broke so they had to do an in frame over haul, when they sold that truck it had close to a million miles on it an it never had a magnetic drain plug... BTW if you want to use one great, just because others do not agree with you does not mean they are very foolish. Oh did you know that a Fleetguard Strapore oil filter will trap particles as small as 5 microns??? If you would like a link to the Cummins video on that filter let me know I'll post it...

FYI oil filter work outside to in. Direct flow from oil sump/pump to filter. If you are using an OEM filter or better than any ferrous metals that would be large enough to cause any damage to engine would be trapped in filter, thus making a filter magnet useless.

Magnetic drain plugs do work but are not necessary. If it gives you piece of mind then use it. Definitely can’t hurt.

Magnetic drain plugs do work in transmissions. Due to the synchros and constant gear mesh you have a lot of mag particles. Most transmission pans that don’t have drain plugs still have a magnet internal of the pan.

The rear diff is different. It comes to a point and the metal has time to get to the magent.
The reason, and primary difference between the motor lubrication system and a differential, is there is no filter element equivalent in a diff.
