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 11):
A lubricating oil composition according to  claim 4  wherein the number of repeat units of formulae (I) to (IV) in the metal-free pre-ceramic polymer is in the range from 2 to 100.
