description | A lubricating oil composition is provided to improve rubbing stability achieving excellent stability by acylating a plurality of second amino radicals existing in the friction modifier in case that one or more second amino radicals exist in a polyamine chain. A lubricating oil composition includes a base lubricating oil, one or more oil soluble phosphorus-containing compounds and one or more polyalkylene polyamine friction modifiers. The hydrocarbyl substituent includes a carbon atom of 6 to 30. |
