Oil Drain Plug

[SilveradoRST]

I ordered a new drain plug (5.3 2019) because mine was becoming a little rusty.   So I ordered 1 new plug and 1 washer.   But when I got the plug it seems like it comes with a blue washer already in place.   The old plug only used the blue washer.  So am I using only the 1 blue washer only?  Or was there originally a blue and black washer used together and some how got lost during my free oil changes?  Watched a few YT videos but couldn’t make out what people had, 1 or both washers.   I know for the oil filter you have to be careful not to double gasket.   So I assume the same rule apply with the oil drain plug but I wanted to be sure I wasn’t missing anything.  As you can tell, I’m stating my self-oil-changing journey.  Never done it before.

You never stack gaskets.  The black gasket you received is good for the tool box in case you damage the blue one.

If you ordered a GM drain plug it comes with a washer already in it.  Use that one.
