Narrative:
Departed on IFR flight. Climbing through 16;000 ft MSL; low oil pressure annunciator on left engine came on. Pressure tape started dropping. I immediately started a 180 turn back; notified ATC; but did not declare an emergency. ATC gave me vectors after I already turned back. As I joined the vector route; I came within 4.9 miles of another aircraft who was #1 for landing; I was #2. If I would have declared emergency; ATC would have cleared me #1 for landing. I secured the left engine and proceeded with a single engine approach and landing. Cause of loss of oil pressure was a dipstick that popped off during flight. I added oil and proceeded to depart. Before departing; I called center at their request.single pilot; there was a lot to do. Aviate first; communicate second. Still; I should have declared an emergency when requesting return. However; left engine oil pressure tape was still in green. When it dropped to red I should have advised ATC and declared.
