润滑油是机械领域不可缺少的物质，主要起到降低摩擦、提高机械运行速度和延长机械寿命得到的作用，在汽车工业尤为突出，其摩擦学行为是导致汽车机械失效和能量消耗的主要原因。因此减少发动机部件摩擦造成的能量损失是实现降低汽车燃料消耗的重要因素。而发动机设计的改良和润滑油配方技术的提高，都可以直接改善汽车燃油经济性，但是改善润滑油配方的成本要远低于开发新型发动机成本。
发动机润滑油一般是由基础油和添加剂两部分组成，基础油大多采用精制的矿物油，高档润滑油的基础油则采用合成油或矿物油与合成油复配而成的基础油。由于发动机工作时产生的高温、高压、告诉、大负荷都将作用于润滑油，其发动机燃料和废气等对润滑油还有侵蚀作用，因此发动机润滑油必须具有良好的粘温特性、清净分散性、酸中和性、氧化安定性、抗磨性等。由于基础油的性能差异和添加剂的种类与含量不同，形成了发动机润滑油质量与粘度的差异。
