I agree, wait til you see a slight drip then replace the whole plug. The rubber rings wear out over time. Mine went after 12 years.

I have seen them on cars that have aluminum oil pans and steel drain plugs. I think they use them so corrosion doesn't build up between the two metals. Aluminum-steel-water and road salt cause a chemical reaction which builds up rust. Just like the rust on the back of aluminum rims on steel hubs. My father-in-law had a 06 Kia Optima and I went to the dealer for the oil filter (once) and it came with the new ring. I did a few more oil changes on that car but went with a Wix filter and started using teflon tape on the threads of the drain plug. Never any drips...

Mine is 2004, lost count of oil changes.
First time I was concerned but haven't worried about it since
