Narrative:

Cruising at 16000' I noticed oil pressure fluctuating on left engine. Fluctuations continued for several mins. The oil light on the cap came on after 3 or 4 mins. At this point I decided to do a precautionary engine shutdown. After I shut it down and did the required checklists. ATC was notified. The company was notified and I decided that sux was the most suitable airport, and had the best crash, fire and rescue units. I descended to 8000' briefed the passenger. We proceeded to sux and made a single engine landing. After landing, taxied to the terminal and deplaned the passenger. Crash fire rescue equipment crews were called and followed us to the ramp. Mechanics found a nts oil line that had cracked. Oil was leaking out under the engine and spread out over the fuselage.
