The present disclosure relates to a non-acidic, sulfur-containing, phosphorus-containing compound of the formula I where R, R, R, R, R, R, and Rare as defined herein. Such a compound may exhibit improved antiwear performance and thermal stability in lubricating compositions.

1,3,2-dioxaphosphorinane, 2-sulfide derivatives for use as anti-wear additives in lubricant compositions

The present disclosure relates to a compound of the formula I or a tribologically acceptable salt, solvate, hydrate, or proadditive thereof, wherein R1, R2 and R4 are as defined herein. Such novel pyrrolidine, or succinimide, derivatives may be useful as friction modifiers in lubricant compositions. This disclosure also relates to a method of using such friction modifier compounds in lubricating fluid formulations to lubricate machine parts, including gear, axle, engine, and transmission parts, and to lubricant compositions containing such friction modifier compounds. 

Pyrrolidine-2,5-dione derivatives for use in friction modification

There is disclosed a lubricant composition comprising a base oil comprising a reduced total amount of cyclobenzene as compared to another base oil. Methods of using the lubricant composition for preventing and/or reducing the deposit formation in an engine are also disclosed.

Lubricant composition

The present invention provides an additive composition comprising (a) at least one ash-containing phosphorus compound prepared by a primary or secondary alcohol or mixtures thereof, and (b) a salt of at least one hydrocarbylamine and at least one hydrocarbyl acid phosphate. Further, the present invention provides a lubricating composition comprising (a) at least one ash-containing phosphorus compound prepared by a primary or secondary alcohol or mixtures thereof, and (b) a salt of at least one hydrocarbylamine and at least one hydrocarbyl acid phosphate, and methods of use thereof.

Lubricating compositions having improved friction properties

There is disclosed herein an additive composition including a compound of formula (III): wherein R, R, R, R, R, R, R, and Rare independently selected from the group consisting of hydrogen, cyano, and hydrocarbyl groups comprising from about 1 to about 30 carbon atoms.

Composition comprising a sulfur-containing, phosphorus-containing compound, and/or its salt, and uses thereof

Lubricated surfaces and lubricant compositions for lubricating a surface. The lubricated surface is provided by a lubricant composition including a base oil of lubricating viscosity, at least one metal salt of phosphorothioic acid, and an ashless, sulfur-free organophosphorus compound providing a metal to phosphorus weight ratio ranging from about 0.25:1 to about 1.0:1 by weight. The lubricant composition is substantially devoid of molybdenum.

Additives and lubricant formulations for improved antiwear properties

Lubricant formulations and methods for producing lubricant formulations are described that provide improved wear protection in engines operated using ethanol-based fuels. The improved wear protection may be provided by an increased amount of overbased calcium detergent present in the formulation.

Engine wear protection in engines operated using ethanol-based fuel

There is disclosed a salt of a sulfur-containing, phosphorus-containing compound. There is also disclosed a method of making the salt.

Salt of a sulfur-containing, phosphorus-containing compound, and methods thereof

In its broadest concept, the present invention relates to an improved gear oil comprising:

Extended drain, thermally stable, gear oil formulations

A lubricant composition comprising a phosphorus-containing compound and a base oil comprising less than about 3% by weight of tetracycloparaffins is disclosed. Methods of making and using the lubricant composition are also disclosed.
