BMW X3 (F25) Service & Repair Manual: Approved final drive oils for front and rear axle final drives with and without limited slip or viscous coupling
2.0 APPROVED FINAL DRIVE OILS FOR FRONT AND REAR AXLE FINAL DRIVES WITH AND WITHOUT LIMITED SLIP OR VISCOUS COUPLING
LIMITED SLIP DIFFERENTIALS
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.
