On climb out from addison airport, in IMC. I looked to my left and found oil streaming back from the engine. The instruments indicated oil pressures and temperatures to be fine. I immediately told departure controller that I needed to go back to addison and proceeded to shut down the left engine. I declared an emergency and flew the ILS approach into addison airport and landed safely. The oil cap was found to be loose. The only logical explanation is that the line person who refueled/filled the oil on the engines did not put the cap on tight. I did not notice that the cap was loose. No damage to persons or property occurred.
