Abstract
The invention provides a lubricating composition containing an oil of lubricating viscosity and an ashless ketone compound with at least one of a hydroxy group and an ether linkage attached to the carbon atom adjacent to the carbonyl carbon of the ketone, especially α-hydroxyketone. The invention further relates to methods of lubricating an internal combustion engine by supplying the described lubricating composition to the internal combustion engine. The invention further relates to the use of the α-hydroxyketone compound as a friction modifier and an antiwear agent.
