Abstract:
The present invention relates to a lubricating composition, particularly marine diesel engine lubricating compositions, comprising: (a) an oil of lubricating viscosity; (b) an asphaltene dispersant comprising an amide group, which may also contain a succinimide group, and which may optionally be used in combination with additional asphaltene dispersants that contain a cyclic headgroup that contains a nitrogen atoms where the additional asphaltene dispersants may also include a succinimide group; and (c) a detergent derived from an alkyl phenol. The invention further provides methods of using such compositions in the operation of engine, particularly marine diesel engines.
