Scheduled servicing of the supercharger is important to keep in the best condition and to prevent failure. The R53 and R52 Mini Cooper S models are fitted with an Eaton supercharger. The supercharger is lubricated and partially cooled by oil located in two reservoirs within the supercharger housing. For BMW / Mini do not offer a change of this oil / service of this part as part of the service schedule. However other manufacturers vehicles utilising the same supercharger recommend servicing at 40,000 miles. .
