DIY: Supercharger oil refilling
The Best of Mercedes & AMG
I found the best way to remove the drain \ fill hex plug fastener was to cut down an old 5mm allen key with my angle grinder as the space is very confined and then use a long ball ended allen to remove it from the SC. I was very careful to remove the plug as the last thing I wanted to do was drop it into the nether lands of the engine (tiny bit nerve racking):

I found that the best way to remove the old oil from the SC after carefully removing the plug was to manually siphon it out using good old lung vacuum rather than using a syringe that worked for others.
I was able to find the perfect 5-mm diameter flexible tube (very important as the hole on the SC is very small) and pushed it as far into the SC as possible (a length of 5.25-in) to draw out the old oil and the total oil capacity of the SC is 125ml. I also placed two floor jacks under the rear of the car to assist the oil draining towards the front.


The old SC oil was extremely dirty and as everyone mentioned had quite a pungent smell. My car has a little over 50K.

As you can see from the above picture the new OEM MB oil is clear and very light weight (low viscosity thus easy to pour) almost like a machine oil.
I did use a 60ml syringe to carefully push the new oil into the SC and also used liquid teflon on the threads of the plug for a good seal. Note that these threads are teflon coated from the factory. Total time required was just over an hour.
Regards.
i changed my sc oil, i could took out like 90ml, and it take 200/220 ml to refill to the bolt, and it is running good and no oil out from sc pulley bolt.

Oil with part number 000 989 62 01 is used for Eaton type supercharger found on M271 engines. The reason for Mercedes service to give this oil when asked about supercharger oil is that this is the only oil they have listed as supercharger oil.
IHI twinscrew superchargers don't need supercharger oil change (according to Mercedes). If oil has to been added then the supercharger is threated as a faulty unit.
Most all of us use the JetII oil and this been posted here on DIY for years now. I check my oil every year and top it off or change it, as it seems to get low first and then turn brown from heat. Low oil is a SC killer!
