Oil was changed 8 mo ago. I took the car to an independent shop. It looks like the axle seal is leaking however he never heard of an rear axle seal leak.
It is a very slow leak that's why it is so hard to tell its origin.
If it wasn't for the occasional drip to the muffler I would have left it alone.
