that assumes that the magnet will catch the metal particles while they are in suspension instead of them settling to the pan, which will happen every time you shut off the engine.

The only way the magnet would be highly effective is if it was stuck to, or very near, the oil pump pick up screen.

and the drain plug adapter still leaves residual oil in the pan, a good bit more than staying with the original style plug. 

 

again, was not looing for a debate on it, just offering a thought

 

Metal oil pans typically have a magnet in the bottom of the oil pan for this purpose, same for transmissions. Ford also has one on the plugs for the rear differential, same as some aftermarket oil plugs, it does actually work even though you have doubts.

 

As for remaining oil it's minimal, when jacked up in the front, and probably less than when the change is done at a place on a hoist or a pit with a standard plug.

 

You can't post something without someone potentially having a counter point. ?

Where do you suspect the ferrous metal comes from that's collected by the magnet?

 

All engines end up with it from the crank, cams, lifters, cylinder walls/sleeves, oil pump, etc. A lot of a motor is still ferrous. Oil doesn't eliminate wear but helps keep it to a minimum, the stuff collected are microparticles, as fine as dust.

Would the below review convince you to purchase?

 

No since 120,000 miles with no engine work is very typical and it is more unusual if it is required now a days. 300k miles or more and planning on keeping vehicle long term possibly.

 

Not saying an aftermarket plug or magnet is required, but it can't hurt and definitely keeps some particles that could speed up wear from going through the system.

Rings & cylinder walls, cam sprockets & chains would likely be the primary sources of ferrous metals...

but not all materials in the engine are ferrous.. which of course makes the magnet irrelevant for those particles, and filter quality paramount.

 

and no. reviews don't convince me to buy anything that I was not already going to buy.
