Have a 2003 3.0 Outback. Noticed that the replaceable Oil Drain Plug crush washer has a flat side and a rounded side. Which side goes up against the Oil Pan???
How tight should I do the Oil Drain Plug??? (Ft-lb / Nm)
Thanks in advance......

The rounded side, as the pan countour is also rounded. The flat side mates to the bolt's flatness.
Dunno the spec, but until someone answers, here's what I do: tighten till I feel the washer crush a bit. I've neither had leaks or difficulty removing it in future changes, so I guess that's okay. Someone with a service manual will surely pop in to give us the word, though I hope.

I made mine halfway between "snug" and "supertight".
