Okay. Can you get a picture of that as well? Clearly this is normally oil and coolant mixed but the cap is clearly marked inter-cooler and you don't add oil to an inter-cooler. The purpose of the inter-cooler is remove the heat from the air as it enters the engine. Cooler air has a higher density which means more oxygen and more oxygen means more fuel. More fuel means more power.
If you put oil in the inter-cooler it would not remove the heat and it would clog the heat exchanger.
If there is oil in the inter-cooler system, it was either put in there, or you possible have a leak in the engine portion which in theory could allow oil in the system. However, this is a sealed and separate system. See the attached diagram. Have you had to add coolant frequently?
