Well yes that’s correct but I don’t agree with this rubbish about “sealed for life”,although there is no combustion contamination and like you say it’s sealed from atmosphere as parts wear over time the oil must get contaminated with different particles of metal etc which is not good so that in my mind says change it.....so I will.The oil in the supercharger is in a sealed environment so cannot get contaminated by combustion products (one of the main reasons to do an oil change on the engine), friction plates (one of the main reasons for changing autobox oil) or water or dust/dirt. Just as there is no need to change diff oil (for the same reasons) there is no need to change supercharger oil.
When you do it can you please let us know the quality of the oil coming out and the steps you took. Pics would be great. I've not herd of anyone doing it, or how often they fail, though I did see a knackered one on a very old Wheeler Dealers once.
Good luck Robb.
Did my supercharger oil a year ago , bourght some from eBay , if you search Eaton supercharger oil or MB supercharger oil there is plenty to choose ( I had used Mobil aircraft turbine oil in the end I think ) .Just thought I'd check the oil in the supercharger when my mechanic has it for a few more days, apparently whilst it looks good, its about 35 mms below the thread of the plug, where can I get the small amount required, would MB stock it, ball park price? Thanks

Did you see my post above ?? .Tried to get the GM12345982 product but it doesnt show their system
Our friends at MB wanted.......for a 500ml bottle of said oil......
How much?
£45.70!!!!
Where can I buy it much more cheaply?

That's a good price . Yep you could get a second refill with 250ml. If you can't get it all out just do another empty/fill in 6 months to use it up .This is the seller I bought off, checked it was fine for my 1999 W202 C230 Kompressor to which he replied yes.
Its a 250ml kit, bar spilling it there should be enough to do a 2nd refill if anyone is interested let me know.
