Narrative:
While in cruise flight at FL410 I was acting as captain and PNF. The flight crew noticed that the left engine oil gauge was reading low and it continued to drop slightly. After running the checklist under 'engine emergency' we determined that a precautionary landing was necessary and that [a nearby airport] was the closest suitable airfield for landing. We declared an emergency and ATC assisted in vectoring the aircraft to [the new destination]. While descending we completed the checklist and left the left engine running since the oil pressure did not decrease to zero. The checklist only prescribed 'land soon as practical' and reduce the power. After the short vector to final; we landed without incident.
