Lower unit oil question

I have pretty much owned every brand out there at one time or another.
When I changed lower unit oil, it always came out looking just like it went in.
My 2017 L4 200 V-rod, drains black as coal. Every time.
This time I even put some in a jar to see if there was any separation.
After two days, none.

Is this a common Merc thing? Just curious. thanks.

It can be. Are you using the Mercury racing gear lube or at least the high performance?

Merc High Performance gear lube. 90 weight
