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 had the same issue with oil drips from the oil pan bolt. I did like I have done on 20+ cars I have owned...turned the crush washer over and reused it for the second oil change. After a couple days my garage floor had some oil on the floor. So I removed the panel and sure enough it was dripping from the oil drain bolt. Bought a 10 crush washers from the Mazda dealership and replaced the crush washer. Cured the issue. I will for now on replace the crush washer at every oil change.
