Would a magnetic drain plug help in a car like a Honda Civic where many engine components are aluminum?





You still have some iron/ferrous components...

cb450sc,
Yes, I use one in my '93 Civic, I usually get a small amount of silver gray slurry on the magnet, mayby a match heads worth. The engine is aluminum, but what about the cam shaft? anything that will keep the oil cleaner, especially fe components, is well worth the effort. Think of it as auxiliary filter.

The most common ones are of low temp (room temp) varieties that as soon as it goes beyond 80~135C, it will loose most of it's magnetic power.




80 deg C= 176 deg F
135 deg C= 275 deg F
Thats one hot room you live in!!!

The only thing that makes me nervous about the whole magnet deal is the possibility of a metal flake breaking loose and causing damage internally. Is this an irrational fear?

FWIW .. I have some rare earth magnets inside the OilGuard ByPass filter on my Duramax Diesel ... they definitely capture ferrous material ...

Bill,
Not going to happen, the neo magnet grabs hold of the metal and won't let go. If you've never experienced one of these incredible strong and compact magnets, just order some from Ebay, you'll become a believer.
