It could be so easy… I searched the complete operating instructions for filling quantities etc., but found with no syllable etas about the servo oil / share number etc. and what comes into the SLC! Same in the net nothing that brings me further! I still have from my SLK servo oil from Mannol 8980 MB 236.3 only I don’t want to just refill it on Good Happiness… Does someone know where to read the filling quantities (of all liquids and not only motor oil) at the SLC, or knows any and if the said mannol 236.3 is also to be used for the SLC, if not what release should the oil have? Should I have overlooked this point in the Bed.Instructions with the Servo Oil??? Greeting Rainer
