Narrative:
Oil pressure (digital) reading turned amber: there was no associated oil pressure warning light. Pulled out QRH and there was no procedure for low oil pressure if it wasn't in the red or there was no associated caution/warning light. At that point noticed oil quantity dropped to zero (again there was no associated caution/warning). Shortly thereafter there was a loud bang and yaw. The engine had shut down. We followed the QRH procedures and declared an emergency. ATC advised ZZZ1 or ZZZ as the nearest. They at first stated erroneously that ZZZ1 had the longest runways but this was corrected. We chose ZZZ since it was the nearest suitable with the longest runways. Landed uneventfully. Recommend that center have airport data for their airspace immediately available.

Title: B767-300 INDICATED LOW OIL PRESSURE FOLLOWED SHORTLY THEREAFTER BY LOSS OF OIL QUANTITY. LEFT ENG THEN FAILED; FLT CREW DECLARED AN EMER AND DIVERTED.
Narrative: OIL PRESSURE (DIGITAL) READING TURNED AMBER: THERE WAS NO ASSOCIATED OIL PRESSURE WARNING LIGHT. PULLED OUT QRH AND THERE WAS NO PROC FOR LOW OIL PRESSURE IF IT WASN'T IN THE RED OR THERE WAS NO ASSOCIATED CAUTION/WARNING LIGHT. AT THAT POINT NOTICED OIL QUANTITY DROPPED TO ZERO (AGAIN THERE WAS NO ASSOCIATED CAUTION/WARNING). SHORTLY THEREAFTER THERE WAS A LOUD BANG AND YAW. THE ENG HAD SHUT DOWN. WE FOLLOWED THE QRH PROCS AND DECLARED AN EMER. ATC ADVISED ZZZ1 OR ZZZ AS THE NEAREST. THEY AT FIRST STATED ERRONEOUSLY THAT ZZZ1 HAD THE LONGEST RWYS BUT THIS WAS CORRECTED. WE CHOSE ZZZ SINCE IT WAS THE NEAREST SUITABLE WITH THE LONGEST RWYS. LANDED UNEVENTFULLY. RECOMMEND THAT CTR HAVE ARPT DATA FOR THEIR AIRSPACE IMMEDIATELY AVAILABLE.
