## Discrepancy

ON FLIGHT 3978 DURING CRUISE THE CAPTAIN REPORTED, NR 1 ENGINE STARTED LOSING OIL AFTER DEPARTURE.  ELECTED TO DIVERT TO GRR DUE TO OIL LEVEL WENT FROM 9 QUARTS TO 3 QUARTS.  IT WAS AN OVERWEIGHT LANDING BUT WAS WELL UNDER THE 360 FEET PER MINUTE SINK RATE.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  THE CORRECTIVE ACTION INFORMATION IS PENDING.
