| Use the following procedure to check and top up Supercharger oil (W11 engine).Owing to the extreme heat and harsh operating conditions, it is a good idea to check the supercharger oil level on a regular basis. MINI does not specifically recommend a supercharger oil service and no oil is available through MINI parts. The supercharger on the MINI is manufactured by Eaton. General Motors uses a similar Eaton supercharger and the GM supercharger oil (GM Part number 12345982) can be substituted. |
