1.0 General Information On Final Drive Oil: Notes

WARNING: This page does not describe the selected car, but rather 76 other vehicles, including the 2009 BMW Z4, 2009 BMW X6, 2009 BMW X5, 2009 BMW X3, and 2009 BMW M6. However, it is still accessible from the selected car via links, so may be relevant.

Final Drive oil or hypoid gear lubricant must conform with the following requirements because of the high loads which occur on the profiles of the hypoid gear teeth:

Load carrying capacity.
Sufficient protection against seizure.
Good wear protection.
Optimal friction and temperature behavior.
Seal compatibility.
Aging resistance.

These and other properties are already contained in brand-name hypoid gear lubricants because of the high content of EP additives (EP = extreme pressure).
