A grease composition is disclosed which is intended primarily for use in constant velocity joints (CV joints), especially ball joints and/or tripod joints, which are used in the driveline of motor vehicles. The grease composition for use in constant velocity joints comprises at least one base oil, at least one thickener, zinc sulfide, at least one copper sulfide and molybdenum disulfide and/or tungsten disulfide. Further, the present disclosure relates to a constant velocity joint comprising such a grease composition.

A lubricating oil composition including a major amount of a base oil, one or more calcium-containing detergents to provide at least 1000 ppmw of calcium, and one or more silicon-containing compound(s) to provide at least 50 ppmw of silicon to the lubricating oil composition, all based on the total weight of the lubricating oil composition, wherein a ratio of ppmw of silicon provided by the one or more silicon-containing compound(s) to the lubricating oil composition to the ppmw of calcium provided by the one or more calcium-containing detergent(s) to the lubricating oil composition is from 0.02 to 1. Methods of using these compositions and silicon-containing detergents are also described.
