An oily intercooler is also an inefficient intercooler. That oily film in your catch can/FMIC is negatively effecting performance. Keeping oil out of the intake tract is the goal.
The oil never really makes it up to the intake manifold so it really never burns much. I see near ambient temps from my FMIC so I am not worried about efficiency since that puts it well into the 90% range. I change copper plugs 2-3 times a year and they are never carbon coated.
Garden hose and soapy water a few times a year keeps a FMIC squeaky clean
