## Discrepancy

CREW NOTICED OIL QUANTITY FOR THE NR 1 ENGINE WAS DECREASING AT A GREATER RATE THAN NORMAL.  INDICATED QUANTITY HAD DECREASED FROM 4 GALLONS TO 2 GALLONS IN 5 HOURS FLIGHT TIME.  PRESSURE AND TEMPERATURE REMAINED NORMAL.  MAINTENANCE CONTROL ADVISED REDUCING POWER WHICH REDUCED CONSUMPTION.  AIRCRAFT DIVERTED TO MSP.  MAINTENANCE REPLACED THE NR 1 ENGINE.
