I serviced my supercharger oil yesterday, the hardest part is getting the fill plug back in...
I didnt even notice the smell, again: the differential oil is wayyyy worse imho!
This was the result (1 year old oil). More pics in my build thread here: https://mbworld.org/forums/c219/8443...ml#post8812105

I just had an Indy shop replace mine at 50k miles. He actually suggests changing it every 50k so I'm good for a long time. Funny thing is I called the local Mercedes dealer and asked them about changing it; there response was this: "I don't even know if that is serviceable". 🤦♂️
I Was supposed to get a follow-up call from them but never heard back. 🤷🏻♂️

For me with an under house garage both oils tend to hang around for some time especially if you spill some.
Your oil looks pretty clean as well for the miles.

@SICAMG Hahah I dont plan on doing to much with the boost to be honest 
But I do replaced the supercharger pulley bearing last year hehe
For now I have these in mind: shorty headers, 82mm TB, bypass valves on the rear mufflers and maybe a 84mm pulley or so (nothing too wild).
