A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition.

Ashless or reduced ash quaternary detergents

A lubricating composition comprising an oil of lubricating viscosity, 1 to 1000 parts per million by weight of titanium in the form of an oil-soluble titanium-containing material, and at least one additional lubricant additive provides beneficial effects on properties such as deposit control, oxidation, and filterability in engine oils.

Titanium and molybdenum compounds and complexes as additives in lubricants

A lubricant comprising (a) an oil of lubricating viscosity; (b) a polyether of number average molecular weight 1000 to 10,000; said polyether comprising alkylene oxide monomer units, where the alkylene group contains 3 to 6 carbon atoms, and ethylene oxide monomer units; and (c) one or more anti-foam agents, where the lubricant has a sulfated ash content of less than about 0.7 percent, is useful for lubricating a stationary gas engine where the engine drives a compressor and where both the engine and the compressor are lubricated with the same lubricant.

Engine lubricants containing a polyether

This invention relates to anthranilate esters and their use in lubricants, such as engine oils. The invention particularly relates to compositions that deliver an ash-free base to a lubricant in the form of a basic amine additive, without adversely impacting seal compatibility and/or degradation, and methods thereof.

Anthranilic esters as additives in lubricants

The invention provides a lubricating composition containing a diarylamine, an aminobenzene and an oil of lubricating viscosity. The invention further relates to the use of the lubricating composition in an internal combustion engine. The invention further relates to the use of the lubricating composition to improve TBN retention.

Lubricating composition with improved TBN retention

A lubricant composition, comprising an oil of lubricating viscosity, a dispersant comprising the condensation product of a carboxylic-functionalized polymer with an aromatic moiety through an amide, imide, or ester linkage, and an oil-soluble titanium compound, exhibits good oxidative stability.

Lubricants containing aromatic dispersants and titanium

An engine fueled by natural gas may be lubricated by providing thereto a lubricant composition of an oil of lubricating viscosity, an overbased monovalent metal detergent in an amount to provide at least about 0.01 weight percent monovalent metal to the lubricant composition, wherein the monovalent metal comprises about 10 to about 30 percent by weight of the total metal content of the lubricant composition, an overbased divalent metal detergent, in an amount to provide at least about 0.005 percent by weight of the divalent metal to the lubricant composition, a dispersant, and a metal salt of a phosphorus acid. The lubricant composition has a sulfated ash of less than about 0.8 percent.

Lubricant for natural gas engines

A lubricating composition comprising an oil of lubricating viscosity, at least 25 parts per million by weight of titanium in the form of an oil-soluble titanium-containing material, and at least 70 parts per million boron in the form of a soluble boron compound such as a borate ester provides beneficial effects on properties such as deposit control, oxidation, and filterability in engine oils and lubrication of engines.

Titanium compounds and complexes as additives in lubricants

A low-sulfur, low-phosphorus composition comprising an oil of lubricating viscosity; a substantially nitrogen-free sufurized olefin antiwear agent; a nitrogen-containing dispersant; and an overbased detergent selected from the group consisting of salixarates, saligenins, salicylates, and glyoxylates; containing less than about 0.1 percent by weight phosphorus, less than about 0.5 percent by weight sulfur, and having less than about 1.2% sulfated ash, is useful for lubricating a diesel engine, exhibiting good antiwear performance.
