Over the next few days I will be changing the oil in the Wife's Tribute. Currently it has a rubber molded drain plug 12mm-1.75. I've always been anal about changing gaskets on drain plugs. Just wandering what you all think. Should I go back with a molded rubber plug or by a new plug with copper gaskets and just change the gaskets. Or any other type gaskets-rubber, fiber, nylon, etc. What do you all think? I just replaced a stripped out drain plug gasket on my parents older Cadillac with a singleoversize plug and a copper gasket. NO LEAKS! I'm honestly considering a Dorman product plug with copper gasket.
