Lubricating oil compositions have low friction properties and anti-wear properties and are excellent in long drain capability. The lubricating oil compositions are particularly suitable for use as a fuel efficient type lubricating oil for internal combustion engines. The lubricating oil compositions contain a lubricating oil additive comprising one or more compounds selected from a specific nitrogen-containing compound, an acid-modified derivative thereof, and an oil soluble metal complex obtained by mixing the nitrogen-containing compound and/or acid-modified derivative thereof with an organic metal salt and/or organic metal complex.
润滑油组合物具有低摩擦特性和抗磨损特性,并且具有出色的长换油期能力。润滑油组合物特别适合用作内燃机的节油型润滑油。润滑油组合物含有一种润滑油添加剂,该添加剂由一种或多种化合物组成,这些化合物选自特定的含氮化合物、其酸性改性衍生物以及通过将含氮化合物和/或其酸性改性衍生物与有机金属盐和/或有机金属复合物混合而获得的油溶性金属复合物。
