Lubricating compositions comprising an azole-acrylic adduct formed by contacting an azole compound with an acrylic. The adduct formed has at least one N-alkyl group comprising at least one acyl. The lubricating composition also comprises a thiadiazole. Methods of lubricating a component of a farm tractor, off-highway vehicle or drivetrain comprising contacting the component with the lubricating composition comprising an azole-acrylic adduct formed by mixing an azole compound with an acrylic. Methods of reducing corrosion in a component. The use of an azole-acrylic adduct in a lubricating composition to reduce corrosion in a component.

Azole derivatives as lubricating additives

A composition comprising an oil of lubricating viscosity and a compound represented by formula (I) wherein: Rand Rare each independently a hydrocarbyl group containing from about 4 to about 18 carbon atoms; p and q are each independently 0 or an integer from 1 to 3, and the sum of p and q is 1, 2, 3, 4, 5, or 6. The composition is effective at swelling seals. 

Seal swell agents for lubricating compositions

A composition comprising an oil of lubricating viscosity and a compound represented by formula (I) wherein: x is 0 or 1; Ris a hydrocarbyl group containing about 4 or about 18 carbon atoms; Ris an aliphatic hydrocarbyl group containing about 1 to about 12 carbon atoms; and y is 0 or 1, which composition is effective at swelling seals. 

The invention relates to a seal swell agent which is a substituted sulfonyldibenzene compound, and lubricating compositions containing the seal swell agent. The substituents on the benzene rings may be hydrocarbyl groups of 4 to 20 carbon atoms or alkylene groups of 1-2 carbon atoms with further functional groups.

A composition comprising an oil of lubricating viscosity and a compound represented by formula (I) wherein x is 0 or 1 and Ris a hydrocarbyl group containing about 4 to about 18 carbon atoms, which composition is effective at swelling seals. 

Seal swell agents for lubrication compositions

A driveline device is lubricated with a composition of an oil of lubricating viscosity and an oil-soluble quaternary ammonium compound, such as a succinimide or succinamide material or dispersant further containing a quaternary nitrogen atom, and a thiadiazole compound.
