Abstract: This disclosure describes low ash lubricating composition achieving passing steel corrosion, passing high temperature deposit formation, and emulsion stability. The lubricating compositions include one or more select corrosion or rust inhibitor chemistries having an oil-soluble acyclic structure with acidic, hydroxy, or amine moieties but being free of imine, imide, and/or amidine moieties.

Abstract: The present disclosure relates to passenger car motor oil lubricating oil compositions having select dispersant and detergent systems to improve at least one of deposits, sludge, oxidization, and wear when using a blend of API Group II base oils with one or more API Group III and/or API Group IV base oils. The dispersant systems herein includes select amounts of boron, nitrogen, and total base number contributions that surprisingly achieve performance even when including higher amounts of the API Group II base oils in the lubricants.

Abstract: A lubricating oil composition comprising greater than 50 wt. % of a base oil of lubricating viscosity, and an additive composition comprising: an amount of one or more zinc dialkyl dithiophosphates (ZDDP compounds) and an amount of one or more viscosity modifiers, wherein an amount of phosphorus (P) in weight percent provided to the lubricating oil composition by the one or more ZDDP compounds divided by the amount of the one or more viscosity modifiers (VM) in weight percent based on a total weight of the lubricating oil composition is a P/VM quotient of more than about 0.0075. The lubricating oil composition can improve resistance to engine deposits and extend oil drain intervals of an internal combustion engine.

Abstract: A lubricating oil composition comprising greater than 50 wt. % of a base oil of lubricating viscosity, and either: a) an additive composition comprising: one or more zinc dialkyl dithiophosphates (ZDDP compounds) and one or more dispersants, wherein the amount of zinc (Zn) in weight percent provided to the lubricating oil composition by the one or more ZDDP compounds multiplied by the contribution of the total base number (TBN) of the one or more dispersants to the TBN of the lubricating oil composition is a multiplication factor Zn*TBNDisp of at least about 0.06; or b) an additive composition comprising: one or more zinc dialkyl dithiophosphates (ZDDP compounds) and one or more dispersants, wherein the amount of phosphorus (P) in weight percent provided to the lubricating oil composition by the one or more ZDDP compounds multiplied by the contribution of the total base number (TBN) of the one or more dispersants to the TBN of the lubricating oil composition is a multiplication factor P*TBNDisp of at least about 0.051.
