I have a 2003 cooper s which has sustained a fatal supercharger fault threw lack of oil. Can any body tell me what oil is used in the supercharger so I can service a recently purchased replacement unit?? Paul (uk)
BP2197 or aeroshell 500 is what I would say.
I did a load if searching around and research a while back at work with oil specs
and this is a far better oil meets and surpasses all the specs of the standard gm/eaton oil
I have been using this in mine for the past 65k miles and in the last three sc I have rebuilt for people. I change it every two years flush both ends out, and have even used the borascope to check the gear wear patterns. How sad I here you cry :-) I use old stick that's out of shelf life are rules and Regs are tight and tbh it's a synthetic third gen oil it does not go off
My MCS has done 100K should I change the oil, top up or leave it? If changing how do I do it (haven't done any Googling yet), there is just a level plug so I syphon out the old?
what do I need to strip out to get to the rear plug? what about adding molybdenum oil additive?
Eaton say for the m45 it's every 20.000 miles but it's well hidden. I do mine every two years.
I personal remove my sc give it a good clean and flush out refill that way your 100% on oil qty
The snout oil plug is easy to with it in the car but the pto end ( water pump end ) you will need to remove the water pump to get to the drain/fill plug.
the problem with the pto end is oil can get sucked out of the res though the oil seal in to the sc airway leaving low or no oil in the pto end so the gears run dry and wear out :-(
Hope this helps
