A lubricating composition including an oil of lubricating viscosity and a benzazepine compound. Methods of using such lubricating compositions are also disclosed.

Benzazepine compounds as antioxidants for lubricant compositions

Lubricant compositions comprising (a) an oil of lubricating viscosity and (b) a phosphonate ester other than a zinc salt. The phosphonate ester may be the reaction product of (i) phosphonic acid or a monomeric ester thereof with (ii) a propanediol having hydroxy groups in both the 1 and 3 positions and one or more of the carbon atoms of the propyl units are substituted with one or more alkyl groups such that the total number of carbon atoms in the propanediol ranges from 4 to 12. The molar ratio of (i) to (ii) may be 0.9:1.1 to 1.1 to 0.9.

Cyclic phosphonate esters for lubricant applications

An additive for a lubricating composition includes an ionic tetrahedral borate compound which includes a cation and a tetrahedral borate anion having a boron atom, the boron atom has at least one aliphatic bidentate di-oxo ligand. The cation may be selected to provide detergent and/or dispersant and/or antioxidant properties to a lubricating composition.

Aliphatic tetrahedral borate compounds for lubricating compositions

The disclosed technology relates to a novel coupled 6-amino uracil derivative, and the use of the coupled 6-amino uracil derivative as a stabilizer in halogen containing polymer compounds. In particular, the disclosed technology relates to the use of a coupled 6-amino uracil derivative as a stabilizer in vinyl chloride compounds, such as, for example, chlorinated polyvinyl chloride (CPVC) compounds.

Coupled uracil compound for vinyl chloride polymer resins

A lubricating composition includes an oil of lubricating viscosity, an N-alkyl naphthylamine, and at least one ashless antioxidant selected from a diarylamine antioxidant, a phenolic antioxidant, and mixtures thereof. The lubricating composition has a phosphorus content of less than 0.15 weight percent. The combination of the N-alkyl naphthylamine and ashless antioxidant provides a beneficial effect on the basicity of the composition without negatively impacting seals performance.

Lubricating composition with alkylated naphthylamine

Thioether-substituted phenols that are the reaction product of a thioether-substituted alcohol or thioether-substituted amine and a phenol with at least one pendant acyl group and have a ratio of sulfur groups to phenol groups of at least 1:1 and uses for thioether-substituted phenols. Methods of lubricating an internal combustion engine by contacting the internal combustion engine with a lubricating composition comprising a thioether-substituted phenol. Methods of reducing deposit formation and/or corrosion in an engine using a lubricating composition comprising a thioether-substituted phenol.

Thioether-containing phenolic compounds
