Narrative:
We departed anc for a round trip freighter at approximately XA15 for bfi. Our aircraft had an MEL item -- #1 oil quantity gauge inoperative -- which requires a mechanic to check and fill oil as required at each fuel stop. At bfi, we unloaded and loaded for return flight to anc. We also fueled. However, I did not check to see if a mechanic svced the oil for #1 engine. We returned to anc and arrived at approximately XG30. The flight was without incident (uneventful). I would say that the time of day (night) and crew changing rest patterns contributed to this oversight.

Title: AN ACR B737 FREIGHTER FLC FAIL TO FOLLOW AN MEL REQUIREMENT TO CHK #1 ENG OIL LEVEL AT EACH REFUELING STOP.
Narrative: WE DEPARTED ANC FOR A ROUND TRIP FREIGHTER AT APPROX XA15 FOR BFI. OUR ACFT HAD AN MEL ITEM -- #1 OIL QUANTITY GAUGE INOP -- WHICH REQUIRES A MECH TO CHK AND FILL OIL AS REQUIRED AT EACH FUEL STOP. AT BFI, WE UNLOADED AND LOADED FOR RETURN FLT TO ANC. WE ALSO FUELED. HOWEVER, I DID NOT CHK TO SEE IF A MECH SVCED THE OIL FOR #1 ENG. WE RETURNED TO ANC AND ARRIVED AT APPROX XG30. THE FLT WAS WITHOUT INCIDENT (UNEVENTFUL). I WOULD SAY THAT THE TIME OF DAY (NIGHT) AND CREW CHANGING REST PATTERNS CONTRIBUTED TO THIS OVERSIGHT.
