The invention relates to a lubricant composition containing ashless TBN molecules. There is provided a lubricant composition comprising: a base oil of lubricating viscosity and an ashless TBN lubricant additive: wherein R1, R2, R3 are each independently hydrogen; a C1 to C6 hydrocarbyl group; a C1-C6 alkyl, aryl or alkoxy group, or a C1-C6 hydrocarbyl group further comprising an ether linkage linking a-O (CH2) n-CH3 group, where n = 0 to 3. 本发明涉及含有无灰TBN分子的润滑剂组合物。提供了一种润滑剂组合物，包含：具有润滑粘度的基础油和无灰TBN润滑油添加剂：其中，R1、R2、R3各自独立为氢；C1至C6烃基基团；C1至C6烷基、芳基或烷氧基基团，或还包含连接-O(CH2)n-CH3基团的醚键的C1至C6烃基基团，其中n＝0至3。
