[At] flight level 340; south of ZZZ; direct ZZZZZ; [the] oil quantity showed 8%. The Captain called Maintenance Control while I flew. I referenced drift down altitude; speed from the FMC and referred to the QRH for low oil pressure checklist and the following engine shutdown checklist since low oil quantity is not included.At approximately XA29; Engine Number 1 oil quantity at 0% and engine oil pressure began fluctuating from 45 PSI to 33 and lower in the amber band. By XA40; oil pressure was approaching red band. At approximately XA40; the Captain and I shut down Engine Number 1. The Captain and I decided along with Dispatch; after discussing with Maintenance Control; that ZZZ was the best location to divert to. I accomplished a visual landing to Runway XXL; backed up by the ILS XXL. Winds were 330/7; autobrake 3. Crash recovery/fire looked over the aircraft after the landing. All clear; we taxied to Gate XX. Taxi on to the gate was uneventful. This does not include all actions that were performed but those I can recall from memory [that] feel important.
[Report narrative contained no additional information.]
