Narrative:

We picked up our aircraft at our maintenance hangar in the morning. This was for the airplane's first flight of the day. Before picking up our passenger we conducted our 'first flight of the day' checks which included a run-up. We then repositioned to the passenger terminal. As I deplaned, I noticed a large puddle of oil under each engine. Oil was dripping everywhere. Upon further inspection we discovered both oil caps were left unsecured by maintenance. It is not our policy or practice for us (the flight crew) to check the security of the oil caps.
