Oil leaking from drain plug?

i do my own oil changes.

i brought my 2015 mazda3 to the dealership for a recall.
they did their usual 360 degree check (or whatever they call it) in addition.

the service rep said the mechanic found slight oil leaking and suggested that i replace the drain plug/washer.

i can see it not being tight. just tighten it, right?
but to buy a new one and replace? ???

How does an oil drain plug/washer fail?

I call that BS, I've got the same crush washer since I did my first OCI.

However, if you didn't tighten it correctly then it will definitely leak.
