Method and system for oil life monitoring

A system for determining a maximum oil change limit of an engine, the system comprising:

• an engine;
• a locating device configured to provide a current location indicator of the engine in response to a current trigger;
• a controller in communication with the locating device, the controller configured to:
• generate a current oil change index using the current location indicator,
• store an at least one prior oil change index,
• generate a maximum oil change limit for the engine using at least one of the current oil change index and the at least one prior oil change index, and
• store the maximum oil change limit.

A vehicle including an engine, the vehicle configured to determine a maximum oil change limit of the engine, the vehicle comprising:

• an engine;
• a GPS receiver configured to provide a current location indicator of the vehicle in response to a current trigger;
• a controller in communication with the GPS receiver, the controller configured to:
• generate a current trigger,
• generate a current oil change index using the current location indicator,
• store an at least one prior oil change index,
• generate a maximum oil change limit for the engine using at least one of the current oil change index and the at least one prior oil change index,
• store the maximum oil change limit,
• receive a last oil change event as an input,
• compare the maximum oil change limit and the last oil change event, and
• output an oil change limit alert when the maximum oil change limit is met or exceeded;
• an output device configured to communicate at least one of the maximum oil change limit and an oil change limit alert;
• and
• wherein the vehicle is one of a hybrid vehicle and an extended range electric vehicle.
