## Discrepancy

DURING CRUISE, THE CREW NOTICED THE NR 3 ENGINE OIL CONSUMPTION TO BE UNUSUALLY HIGH.  THE OIL CONSUMPTION DECREASED WITH LOWER POWER SETTINGS SO THE AIRCRAFT DIVERTED TO MSP FOR MAINTENANCE.  THE ENGINE WAS NOT SHUT DOWN AND THE FLIGHT WAS COMPLETED WITHOUT FURTHER DIFFICULTY.  UPON ARRIVAL IN MSP, THE AIRCRAFT WAS REMOVED FROM SERVICE AND THE NR 3 ENGINE WAS CHANGED.  EXACT PART CAUSING DIFFICULTY TO BE DETERMINED.
