1.0 General Information on High Temperature Multi-Purpose Grease
High temperature multi-purpose grease consists of a lithium complex soap in a mineral oil product with a selected combination of additives. Extremely fine soap is contained in the oil, and serves as the basic ingredient.
This lubricating grease possesses the following properties
- Very good thermal resistance and penetration stability
The structure and consistency must be maintained over long service life with temperatures from -22°F to +302°F (-30°C to +150°C) in continuous operation and very high loads.
- Oxidation stability
A lubricating grease contains effective inhibitors (which limit or prevent chemical reactions) in order to stop oxidation at very high operating temperatures.
- Water resistance and corrosion inhibition
A high temperature multi-purpose grease is water resistant. At the same time lubricated parts are given maximum protection against rust by the corrosion inhibitors.
2.0 Approved High Temperature Multi-purpose Grease

3.0 Approved Final Drive Oils For Front And Rear Axle Final Drives With And Without Limited Slip Or Viscous Coupling
Mineral based final drive oils are no longer recommended due to the release of synthetic final drive oils for all vehicles with or without limited slip differentials.

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.
