Narrative:

During cruise from mexico city to san francisco international, #2 engine oil quantity went to zero. #2 engine was shut down. Then, we diverted to cuu. In-flight engine shutdown, qrc for driftdown, and all other appropriate checklists were completed prior to landing, including the overweight landing checklist. The captain and I talked to maintenance and dispatch about the engine problem but did not deal with the overweight landing. Contributing factors for this oversight include but are not limited to: 1) dealing with the more critical issue of repairing the engine. 2) language barriers. 3) diversion. 4) the lack of familiarity with procedures in mexico with respect to telephones/facilities for the passenger, etc. Anyway, after departing cuu and reaching cruise altitude, the captain remembered that we didn't tell maintenance about the overweight landing (as requied in the operations manual). We immediately notified our maintenance personnel via ACARS.
