Last year, my then girlfriend/now wife bought a used '99 Grand Am. First time I changed the oil, I noticed the drain plug had a magnet on the tip with a fair bit of metal shavings on it. Of course, under my care there is practically nothing on it any more.
I'm thinking a drain plug like that is a good idea. Does anybody know where I can get one for my '02 Ford Ranger and my parents' cars?
