Attention: On vehicles with self-locking differential (extended range of equipment) high grade oil must be used. High-grade oil can be filled into all rear axle differentials.
The grades approved by BMW are, for example:
- oil for rear axle gearboxes BMW Syntetik MSP,
- transmission oil Aral BS-LS,
- Avia Hypoid 75W-90 LS,
- Castrol SAF-XLS, Shell MLS-BMW gear oil,
- Veedol SAF 55.

Caution: The oil is viscous, so do not add too much oil at once. Maintain pauses and substitute a vessel to collect the flowing oil.
Screw in the filler plug with a tightening torque of 55 Nm.
