HYDROXY FUNCTIONALIZED ASHLESS ADDITIVE

摘要

The disclosed technology relates to hydroxy functionalized ashless additives useful in engine oil compositions due to their ability to reduce deposits, particularly deposits seen in turbocharged direct injection (TDI) engines. The described additives include ashless saturated compounds having a long chain hydrocarbyl polymer terminated by a hydroxyl group. The disclosed technology also relates to lubricant compositions containing the described additives, processes of making the described additives, and methods of using the described additives.
