They used to be advertised all over a few years ago, now I can't find one
anywhere.

Using Word, I made up a page of stickers for oil/filter changes. I keep
them with the logbooks, and peel & stick as needed.

As someone else mentioned, I don't know if they'll stick forever -- but
there's always clear tape...
