Aircraft
After starting the aircraft; I ran through my normal procedures including flows and checklists. I began to taxi out of the assigned parking [Company] holds for ZZZ which faces South on the helicopter pads for Runway XX. This included me making a right 180 degree turn to enter taxi way 'A'; during the turn I was ensuring I had adequate distance to the other aircraft parked on the ramp as well as informing traffic of my intentions. Once aligned on taxi way 'A' I began my taxi flow. I finished my flow approximately 50 ft from the intersection of 'A' and Runway XX. To which I made a radio call announcing my intentions to cross; cleared both directions to make sure there wasn't any landing traffic; and finally reached down to turn on my lights as per [Company] runway crossing procedures. I crossed the runway and announced I was clear and would continue northbound on 'A' for Runway XX. I reached down and flipped off my lights and when I looked back up I noticed my 'L OIL PRESS' light had illuminated. I looked downed at my oil pressure gauge and confirmed the oil pressure level was just at '0'. My oil temperature was on the rise but had not yet exceeded red line so I ran the emergency flow for an engine fire on the ground. Shutting down both engines. The left engine then began to smoke greater than normal out of the exhaust stack. The winds made it difficult to tell if it were coming only out of the exhaust stacks or the cowling. The engine smoked for a few minutes then slowly stopped. I called Airport Ops to come tow me in. Then called Dispatch and informed them of the situation. Once the ground crew arrived; I exited the aircraft and began a basic inspection on the left engine. I opened the cowling and observed the oil dipstick was too hot to remove and check at that time. I then spoke with Maintenance and the [Operations Control] to begin coordinating the next plan of action.
