Narrative:

Upon leveling at FL250 we received a right engine oil pressure warning message. Oil pressure was fluctuating between 26 and 33 psi. We complied with the QRH and monitored the engine. We contacted dispatch and maintenance; and discussed the situation. Approximately 5 mins later the oil pressure dropped below 25 psi; thus requiring the engine to be shut down per the QRH. An emergency was declared with a diversion to ZZZ. A single-engine approach and landing was made with crash fire rescue equipment standing by. We taxied in with no further incident.
