ADDITIVE PACKAGE AND LUBRICATING OIL COMPOSITION
An additive package is disclosed for preparing an automotive crankcase lubricating oil composition for an internal combustion engine. The additive package is made by admixing: (i) 50 mass % or less of an oil of lubricating viscosity; (ii) 50 mass % or less of at least one overbased metal detergent, preferably at least one overbased metal hydroxybenzoate detergent; (iii) 50 mass % or less of an oil-soluble block or graft co-polymer of at to least one polymeric block A which is derived from a hydroxycarboxylic acid and at least one polyalkylene block B which is a residue of a polyalkylene glycol, and (iv) optionally, at least one further additive selected from a dispersant, an antioxidant and/or an antiwear agent.
The additive package includes less than 2.00 mass % preferably less than 1.50 mass %, of a friction modifier which is a monoester of a C.sub.5 to C.sub.30 carboxylic acid and which is free of nitrogen.
Component (ii) is preferably an overbased metal hydroxybenzoate detergent.
Component (iii) acts as a friction modifier and can be used as a replacement for a friction modifier such as glycerol monooleate.
The additive package exhibits improved stability.

Composition and Method of Manufacturing Overbased Sulfonate Modified Lithium Carboxylate Grease
An overbased sulfonate modified lithium carboxylate grease composition and method of manufacture comprising overbased calcium sulfonate, overbased magnesium sulfonate, or both added to a source of lithium hydroxide, base oil, and optionally one or more acids when a complex grease is desired. When overbased sulfonate is added, the amount of dicarboxylic acid relative monocarboxylic acid may be reduced. Additionally, the amount of lithium hydroxide added may be less than stoichiometrically needed to react with the acids. A sulfonate modified lithium grease with improved thickener yield and dropping point may be made without multiple heating and cooling cycles or using a pressurized kettle.
