What happened to the days when they used metal oil plugs and oil plugs that didn't need a new crush washer every time you changed the oil. The factory supplied oil plug would last the life of the car as long as some mechanic that though he was Godzilla didn't get ahold of it.It's one of those plastic ones. They say only for one use but I've used them for more than one oci. I think Ford uses something similar.
