Abstract:
The disclosed technology relates to a lubricating composition comprising an oil of lubricating viscosity and an ashless basic amine additive selected from a N-aralkyl α-carbonyl functional amine. The basic 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 amine additives of the disclosed technology simultaneously achieve seal compatibility, deposit, and corrosion control.
