摘要： 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.

摘要： The invention provides lubricating composition comprising: an oil of lubricating viscosity, and an oxyalkylated hydrocarbyl phenol, wherein the oxyalkylated hydrocarbyl phenol is substituted with at least one aliphatic hydrocarbyl group of 40 to 96 carbon atoms, and wherein the oxyalkylated hydrocarbyl phenol is substantially free of aromatic hydrocarbyl groups. The invention further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The invention further relates to the use of the oxyalkylated hydrocarbyl phenol in the lubricating composition to a passenger car internal combustion engine at least one of (i) control of fuel economy, (ii) control of corrosion, (iii) cleanliness, and (iv) control of bore wear.
