A first purpose of the present invention is to provide a lubricant composition that achieves extended anti-shudder durability without causing a decrease in the metal-to-metal friction coefficient, even when the viscosity of the composition is reduced. A lubricant composition characterized by comprising (A) a lubricant base oil, (C) (C-1) a succinimide compound or boronated succinimide compound having a weight-average molecular weight of 4,000 to 7,000, (C-2) a succinimide compound or boronated succinimide compound having a weight-average molecular weight of more than 7,000 to 10,000, and (D) (D-1) an amide-based friction modifier.
本发明的第一个目的是提供一种润滑油组合物,该组合物即使在降低组合物粘度的情况下,也能延长防抖耐久性,而不会导致金属与金属之间的摩擦系数降低。一种润滑剂组合物,其特征在于包含(A)润滑剂基础油;(C)(C-1)重量平均分子量为 4,000 至 7,000 的琥珀酰亚胺化合物或硼化琥珀酰亚胺化合物;(C-2)重量平均分子量大于 7,000 至 10,000 的琥珀酰亚胺化合物或硼化琥珀酰亚胺化合物;以及(D)(D-1)酰胺基摩擦改进剂。
