I've only gotten moisture from mine so far. No grease or dark stuff that I've seen yet. I haven't taken mine apart cause its just got a little over 2 hours on it. I do have a habit of putting a paper towel down below the drain line so I can see if there is anything coming out other than moisture when I bleed the system.
I've got an inline filter between the compressor and the fill hose end. I check it after every use and it has not had any moisture make it down the hose to that filter yet. I'm pleased with it so far. I did add an external digital temp sensor to the pump head next to the factory sensor. I like to be able to "KNOW" how hot it is when its running. Also added LED lights to the water tank so I can see the pump working without having to remove the tank cap while it's pumping. I also 3D printed a bracket to fit over the pressure gauge and it has a LED in it pointing down to light up the gauge housing so I can see it better. And finally I put on an hour meter to keep track of run time.
Thx

Perhaps you "haven't yet", but you will see the dark grease coming out. It has to, as the air line is the ONLY place it can go.
I took mine apart the day I got it. The engineer in me wanted to see "what makes this tick?". And I shared it so others wouldn't have to do the same.
