Anyone have a catch can? & fuel dilution

First time post... I ordered a new Impala LT with the 3.6, leather, Bose stereo & nav., etc. Reason for not ordering the 2LT was the sunroof, takes up too much headroom for me (I'm 6'2"), and a few thou less purchase price helps too. I ordered in late February, should be here soon.
Anyway, I have a catch can (Elite) waiting to install. I'm convinced it won't hurt anything, and it should help reduce intake valve deposits. I have a spare GM PCV to intake hose to reinstall if needed (and remove catch can), to avoid any possible warranty hassle in the future. Does anyone here have a catch can? Where did you mount it, and does it "catch" much oil?
Also wondering about DI fuel dilution if the oil. Somewhat of an issue with Honda's 1.5 L turbo from what I hear, but haven't heard of any dilution issue with our 3.6.
Interested to hear your opinions and knowledge...
