Patent ID: 10961481

Abstract:
Lubricating compositions comprising a thiol-carboxylic adduct that is the reaction product of a thiol and carboxylic acid and/or a carboxylic acid derivative. The lubricating composition also comprises an antiwear agent. Methods of lubricating an internal combustion engine comprise contacting the internal combustion engine with a lubricating composition comprising a thiol-carboxylic adduct that is the reaction product of a thiol and carboxylic acid and/or a carboxylic acid derivative. Methods of reducing lubricant oxidation and/or corrosion in an internal combustion engine with a lubricating composition comprising a thiol-carboxylic adduct that is the reaction product of a thiol and carboxylic acid and/or a carboxylic acid derivative. The use of a comprising a thiol-carboxylic adduct that is the reaction product of a thiol and carboxylic acid and/or a carboxylic acid derivative to reduce lubricant oxidation and/or corrosion in an internal combustion engine.
