Limited Slip Differentials: Notes
WARNING: This page is about a different variant/trim than selected.
With the introduction of the Z3 roadster a new synthetic final drive oil for all vehicles with a multi-plate limited-slip differential has been released. The new BMW final drive oil SAF-XJ will replace the old final drive oil SAF-XLS.
The SAF-XLS final drive oil is not to be used in the final drive of the Z3 roadster.
Use only the SAF-XJ in the final drive of the Z3 roadster.
NOTE:
If a non-limited slip differential oil is used in a limited slip differential a whining or chattering sound can be heard on very tight turns and will eventually result in a failure of the differential.
