Abstract: A lubricating oil composition for diesel oil vehicle comprises lubricating base oil, in which the composition further comprises triazine compound. The wheel rim power of the diesel oil vehicle is increased by 8-10%, the carbon smoke particulate discharge in tail gas is reduced by 30-50%, oil saving rate is high up to more than 10% and the oil change-over period of machine oil is 2-3 times of that of a conventional one; the discharge fully meets the standard, at the same time eliminates the bad smell and taste of the raw oil, the tail gas discharge of currently used vehicle or new vehicle meet the national standards by using the lubricating oil composition provided by the present invention.
