Oil change
Have your oil changed only by a BMW center or

Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
continuously approves specific oils after con-
firming their suitability for use in its vehicles
with extensive testing.
Only use approved BMW High Performance

If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW center will be glad to answer

formance Synthetic Oil or other approved syn-
thetic oils.
