Abstract:
A lubricating composition comprises an oil of lubricating viscosity, a metal-free pre-ceramic polymer and one or more co-additives. The metal-free pre-ceramic polymer comprises a plurality of repeat units which do not contain oxygen. The pre-ceramic polymers provide the lubricating oil composition with antiwear properties. Also described is a method of lubricating an internal combustion engine and the use of a lubricating oil composition containing a pre-ceramic polymers to inhibit wear in an internal combustion engine.

Claim (Index 15):
A lubricating oil composition according to  claim 1  wherein the metal-free pre-ceramic polymer comprises a mixture of a compound of structure (VII): where R 1 , R 2  and R 8  are independently hydrocarbyl groups containing 1 to 30 carbon atoms, provided that at least one of R 1 , R 2  and R 8  contains at least 3; and a compound of structure (VIII): where R 1  and R 2  are independently hydrocarbyl groups containing 1 to 30 carbon atoms, provided that at least one of R 1  and R 2  contains at least 3 carbon atoms.
