The change engine oil light should come on briefly as a bulb check when you start the engine. If the light does not come on, have it serviced.

If the change engine oil light comes on and stays on after you start the engine, have the oil changed.

For additional information on when to change engine oil for gasoline engines or DURAMAX® diesel engines, see Engine Oil and Scheduled Maintenance . To reset the change engine oil light, see Engine Oil Life System .
