A composition obtained by reacting an O,O'-dialkyldithiophosphoric acid with a hydroxyalkyl acrylate or a hydroxyalkyl methacrylate, and reacting the product thereof with a dialkylphosphite provides good antiwear protection.

Nitrogen-free phosphorus compounds and lubricants containing the same

A lubricant composition of an oil of lubricating viscosity and a phosphite ester reaction product of a monomeric phosphorous acid or an ester thereof with a first alkylene diol having two hydroxy groups in a 1,4 or 1,5 or 1,6 relationship and a second, alkyl-substituted, diol being a substituted 1,3-propylene diol, exhibits good wear and frictional performance.

Mixed phosphorus esters for lubricant applications

The invention provides a lubricating composition containing an oil of lubricating viscosity and a sulfurized aromatic amine compound, especially sulfur coupled aniline. The invention further relates to methods of lubricating an internal combustion engine by supplying the described lubricating composition to the internal combustion engine. The invention further relates to the use of the sulfurized aromatic amine compound as a TBN booster and an antioxidant.

Lubricating composition containing an ashless TBN booster

A lubricant composition comprising (a) an oil of lubricating viscosity; (b) at least two nitrogen-containing materials, comprising (i) at least one amide of the formula RC(O)NRRand (ii) at least one tertiary amine being represented by the formula RRNRwhere Rand Rare alkyl groups of at least 6 carbon atoms and Ris a polyhydroxyl-containing alkyl group or a polyhydroxyl-containing alkoxyalkyl group; (c) a functionalized dispersant component, and (d) at least one diallyl phosphite, provides good lubricant performance for a continuously variable transmission.

Continuously variable transmission fluid with extended anti-shudder durability

A lubricant of (a) an oil of lubricating viscosity; (b) a block copolymer of (i) a hydrophobic first block of Calkyl (meth)acrylic units having an average total number of carbon atoms of at least 8; and (ii) a second block of (meth)acrylic units, at least some units of which comprise a heteroatom imparting polar character to the block; (c) an overbased calcium detergent; (d) a phosphorus-containing anti-wear agent that does not contribute to the metal content of the lubricant; and (e) a friction modifier suitable to reduce the static coefficient of friction at a metal-composition interface, is suitable for lubricating a farm tractor.

Farm tractor lubricating composition with good water tolerance

The disclosed invention relates to a multigrade lubricant composition which can be used for numerous lubricant applications, but is particularly useful for lubricating a diesel engine. The lubricant composition comprises an oil of lubricating viscosity, a detergent, a dispersant, a viscosity index improver, and a combination of anti-foam agents. The lubricant composition may be used for providing enhanced fuel economy and avoiding air entrainment problems when used in lubricating diesel engines.

Lubricant composition comprising anti-foam agents

The present invention relates to a method of lubricating a tractor with a lubricating composition containing: an oil of lubricating viscosity and a sulphur-free phosphorus-containing salt of either (i) a hydroxy-substituted di-ester of phosphoric acid, or (ii) a phosphorylated hydroxy-substituted di- or tri-ester of phosphoric acid.

Method of lubricating a tractor hydraulic

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.

Diesel lubricant low in sulfur and phosphorus

The present invention relates to a lubricating composition containing a corrosion inhibitor compound and a mixture of two or more dispersants, wherein 0 mole % to less than 50 mole % of the second dispersant molecules contain a carbocyclic ring. The invention further provides a method for lubricating a mechanical device using the lubricating composition.

Multi-dispersant lubricating composition

The disclosed invention relates to a functional fluid comprising: at least one oil of lubricating viscosity; at least one detergent, the detergent contributing an amount of metal to the functional fluid equal to a concentration in the range from about 0.015 to about 1% by weight of the functional fluid, the detergent contributing an amount of basicity to the functional fluid equal to a total base number in the range from about 0.3 to about 2; and at least one friction modifier, the friction modifier comprising at least two hydrocarbyl groups attached to a polar group or atom (eg., a nitrogen atom).

Functional fluid

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.
