Interesting.@DanW
Just stumbled back to this thread today...
When I posted to you in this thread, I was thinking the JL had an aluminum oil. (It does not)
Anyway, a month later I attached a 175 lb. pulling force, Rare Earth Magnet to the bottom of the metal oil pan.
I remove the magnet after the motor is off and just before dropping the oil. After oil is dropped, I replace the magnet.
I'm sure the oil plug magnet pales in comparison to the Earth Magnet in gathering up metal.
