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.
