Display Possible cause/consequence Check Engine Oil At Next Refueling Possible solution Check the engine oil level ( page 327) and add engine oil as required ( page 328). If you must add engine oil frequently, have the engine checked for possible leaks. ù The engine oil level has dropped to approximately the minimum level. When the message Check Engine Oil At Next Refueling appears while the engine is running and at operating temperature, the engine oil level has dropped to approximately the minimum level. When this occurs, the warning will first come on intermittently and then stay on if the oil level drops further. Visually check for oil leaks. If no obvious oil leaks are noted, continue to drive to the nearest service station where the engine oil should be topped to the required level with an approved oil specified in the Factory Approved Service Products pamphlet. For information on approved engine oils, refer to the Factory Approved Service Products pamphlet (USA only) or contact an authorized Mercedes-Benz Center. !
