I realize that is pretty unlikely, but I had magnets I wasn't using for anything else, and I can't imagine how it could hurt.

And as a bonus, I noticed a 1000% mpg increase as soon as I did it!!

(ok, maybe not that last part)
Quite a few rigs use magnets in the oil drain plug to catch ferrous metal, when you find a bunch at an oil change it's time to sell the car. Flip side of that if you see a car advertised as just had an oil change/tune up steer clear.
