  • Patent number: 10513667
    Abstract: The present invention provides a lubricating composition comprising: an oil of lubricating viscosity; 3 wt % to 30 wt % of an alkaline earth or alkali metal sulphonate detergent; and an oil-soluble polyalkylene glycol having a distribution of molecular weight such that the molecules thereof have a weight of 2500 to less than 10,000 Daltons and comprise 0.05 wt % to 3 wt % of the lubricating composition. The invention further provides a method of lubricating a 2-stroke internal combustion engine cylinder liner (and piston) with the lubricating composition.

  • Patent number: 8877694
    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.
