  • 权利要求: 1. A lubricant composition comprising: a base oil of lubricating viscosity and an ashless TBN lubricant oil additive: wherein R1 is optionally a C5 to C12 alkyl group optionally containing an ether linkage, and R2, R3, R4 and R5 are each independently straight or branched chain C1 to C5 alkyl groups.2. The lubricant composition of claim 1, wherein the ashless TBN lubricant oil additive is 3. The lubricant composition of claim 1, comprising the ashless TBN additive in weight % based on the weight of the final lubricant oil formulation between about 0.1 weight % to about 10 weight %.4. The lubricant composition of claim 1, comprising base oil in a weight % based on the weight of the final formulation of between about 63% and about 98.9%, an ashless TBN additive in weight % based on the weight of the final lubricant oil formulation between about 0.1 wt % to about 10 wt %, a viscosity modifier in a weight % based on the weight of the final formulation of between about 0.1 wt % and about 2 wt %, and an additive package in a weight % based on the weight of the final formulation of between about 1 wt % and about 25 wt %.
