That's really interesting, a plug with an O ring in the threads to help
the seal and prevent the plug from vibrating out.  (Does that ever happen?)

The Amazon page raises some questions, some answered by the
manufacturer's web site:

https://smartoplug.com/product/r6-smart-o-oil-drain-plug-sump-plug/

In particular the FAQ's (sic) page:

https://smartoplug.com/faqs/

"SMART-O is reusable, but for optimum performance, we recommend changing
the plug once a year."

If the O ring gets damaged, replace the whole plug.

They offer kits with an "assortment of top washer" (sic).

The FAQs say the washer is mostly to protect the oil pan surface.  The O
ring provides the seal.  The plug is to be installed "as the OEM plug is."

There's a washer on the plug in the photos, but not in the little
cartoons that show how it works.  The FAQs include some discussion of
the washers.
