The disclosed technology relates to a lubricating composition comprising an oil of lubricating viscosity and an ashless basic amine additive selected from a secondary amine containing α-carbon aromatic substitution. The basic secondary amine additives used in the lubricating oils of the disclosed technology impart basicity measured as total base number (TBN) without adding sulfated ash. Lubricating oils containing the basic secondary amine additives of the disclosed technology simultaneously achieve seals compatibility, deposit, and corrosion control.

Basic ashless additives and lubricating compositions containing same

The disclosed technology relates to a lubricant composition for automotive gears, axles and bearings, the lubricant composition containing an oil of lubricating viscosity and a metal thiophosphate compound, such as zinc dialkyldithiophosphate, as well as a method of obtaining extreme pressure performance in automotive gears, axles and bearings at lower sulfur content than is typical, by lubricating such automotive gears, axles and bearings with a lubricant composition containing a metal thiophosphate compound, such as zinc dialkyldithiophosphate.

Composition and method for lubricating automotive gears, axles and bearings

The instant disclosure generally relates to lubricating compositions having an oil of lubricating viscosity, an ashless phosphorus-containing antiwear agent an alkaline earth metal detergent, an ashless antioxidant, and an ashless dispersant where the lubricating compositions are substantially free of zinc and methods of lubricating an engine with such lubricating compositions. The instant lubricating compositions are useful as alternative lubricating compositions the reduce and/or eliminate zinc to achieve a desired performance goal of the lubricating composition.

Zinc free lubricating compositions and methods of using the same

The disclosed technology relates to an automotive or industrial gear oil for automotive or industrial gears, as well as axles and bearings, the automotive or industrial gear oil containing an oil of lubricating viscosity, an optional phosphate and/or thiophosphate compound, a particular sulfurized olefin, and a metal thiophosphate compound, such as zinc dialkyldithiophosphate, as well as a method of improving automotive or industrial gear operating efficiency and temperature by lubricating such automotive or industrial gears with the automotive or industrial gear oil.
