BMW X3 Service & Repair Manual / Driveline+Axles / General information on high temperature multi-purpose grease

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 -22ºF to +302ºF (-30ºC to +150ºC) 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.
