Synopsis
Flight Crew reported loss of oil pressure during cruise with the #2 Engine. Flight crew performed an in flight shut down of the affected engine and completed a diversion.
Narrative
While at a cruise altitude of FL 370 we were both alerted to a white flashing box around our engine instruments. Upon assessment; we concluded that we were rapidly losing engine oil from the number 2 motor. We continued to assess the situation to assure it was not an indication problem. When the quantity continued to drop and the oil temperature started to rise; the Captain called for the Low Oil Pressure QRH checklist. At this point; the Captain requested a descent to a lower altitude knowing that an inflight engine shutdown was likely imminent. We continued with the QRH procedure for low oil pressure; which led us to The Inflight Engine Shutdown Checklist. While running the Shutdown Checklist just prior to shutting the engine down we started to experience an alternating flashing red oil temperature and amber Oil Pressure indication. The engine oil quantity was now reading zero. Engine shutdown was completed; with coordination with ATC to divert to ZZZ. [Priority handling was requested] at this point. We coordinated with the Flight Attendants and advised them of the situation and to secure the cabin for landing in ZZZ. The Captain advised the Passengers via the PA; that we were diverting to ZZZ and that our #2 engine was 'Not quite performing to standards.' The Captain also informed them that fire equipment would be standing by; as standard operating procedure and not to be alarmed. Landing in ZZZ was uneventful. We cleared the runway and asked for ARFF to check the aircraft exterior for any abnormalities. None were noted. We were under max landing weight and ran made the brake cooling module; which allowed for a normal taxi to the gate. We taxied to the gate and deplaned.
