Narrative:

While en route at FL310, we received a triple chime master warning message 'left engine oil pressure.' the pressure was coming in and out of the red zone and engine itt was slowly increasing. Performed QRH procedures and counseled with our maintenance department. We shut down the left engine and diverted to cmh. Maintenance found the engine to be over-svced with oil and deferred the automatic oil replenishment system.
