Our first GDI vehicle and with concerns of carbon build-up on the back sides of the intake valves, I decided to install an Oil Catch Can. The version I chose is from ADD W1: www.addw1.com/
I installed the catch can when the Forester was at 1000 miles. After 4000 miles I was able to suck out 26ml of oil (surprisingly high amount in my opinion). Now the exact makeup of this dark oily fluid isn't actually 100% motor oil. It's infused with gasoline as well (I could smell it).
Read the following articles that explain GDI (Gasoline Direct Injection) and how it compares to Port Fuel Injection. Note that some manufactures use both (I recall finding a Mercedes Benz having such setup). I can only imagine the reason is to help clean off the backs of the intake valves while also providing the lower emissions and power improvements of GDI.
