Narrative:
En route noticed oil quantity dropping slowly. We monitored the oil quantity and when it fell to about 6 quarts we started conferring with maintenance. The QRH and maintenance control indicated continued engine operation unless oil temperature or pressure became abnormal. When oil pressure started to drop; we advised ATC that we would be diverting. We shut down the engine as the oil pressure dropped out of the green arc. The shutdown checklist was completed by the time the oil pressure dropped to about 25 psi. We landed uneventfully about 20 mins later.

Title: FLT CREW OF WDB DIVERTS TO NEARBY ARPT WHEN ONE ENGINE IS SHUT DOWN DUE TO LOSS OF OIL QUANTITY AND PRESSURE.
Narrative: ENRTE NOTICED OIL QUANTITY DROPPING SLOWLY. WE MONITORED THE OIL QUANTITY AND WHEN IT FELL TO ABOUT 6 QUARTS WE STARTED CONFERRING WITH MAINT. THE QRH AND MAINT CTL INDICATED CONTINUED ENG OP UNLESS OIL TEMP OR PRESSURE BECAME ABNORMAL. WHEN OIL PRESSURE STARTED TO DROP; WE ADVISED ATC THAT WE WOULD BE DIVERTING. WE SHUT DOWN THE ENG AS THE OIL PRESSURE DROPPED OUT OF THE GREEN ARC. THE SHUTDOWN CHKLIST WAS COMPLETED BY THE TIME THE OIL PRESSURE DROPPED TO ABOUT 25 PSI. WE LANDED UNEVENTFULLY ABOUT 20 MINS LATER.
