Narrative:

#1 engine oil quantity gradually decreased during cruise -- eventually to zero (0) qts. Oil quantity gauge had been on MEL, but was repaired prior to flight. Upon reaching zero qts, the oil pressure began to decrease from 44 psi to approximately 18 psi -- whereupon we proceeded with the 'low oil pressure' procedure. #1 engine was shut down and we proceeded to the nearest suitable airport for an uneventful landing. Postflt revealed no oil in sight gauge -- oil in exhaust area.

Title: A320 FLT CREW HAS LOSS OF OIL QUANTITY AND PRESSURE WHILE ENRTE AND DIVERT TO NEAREST SUITABLE FIELD.

Narrative: #1 ENG OIL QUANTITY GRADUALLY DECREASED DURING CRUISE -- EVENTUALLY TO ZERO (0) QTS. OIL QUANTITY GAUGE HAD BEEN ON MEL, BUT WAS REPAIRED PRIOR TO FLT. UPON REACHING ZERO QTS, THE OIL PRESSURE BEGAN TO DECREASE FROM 44 PSI TO APPROX 18 PSI -- WHEREUPON WE PROCEEDED WITH THE 'LOW OIL PRESSURE' PROC. #1 ENG WAS SHUT DOWN AND WE PROCEEDED TO THE NEAREST SUITABLE ARPT FOR AN UNEVENTFUL LNDG. POSTFLT REVEALED NO OIL IN SIGHT GAUGE -- OIL IN EXHAUST AREA.
