hmm... were you running rich before this?
only reason i ask (and this is a LOOOOOONG shot) is that maybe there is an oil leak in your turbo somewhere, basically the unburned gas is leaking into the oil feed/drain system on your turbo and when it goes back into the pan (and gets circulated through your engine) thats where the smell is coming from.
the other reason i asked if it was truly contaminated/milky or just smelled is b/c then you can kinda check some things off if it just smells and isn't milky. gas breaks oil down and will cause it to run extra thin, my previous swap (and the retard who put my injectors in) put 555cc injectors on a 8 psi t25.... needless to say he soaked the cylinders and ruined my oil (175 miles after the swap). i did 2 oil changes and 3 quarts straight flush to get it all out. its irritating but i would rather spend 50 bux to get it right then be wondering.
that being said, if you're worried about it and didn't have issues with the car previous to the oil and the turbo is fine etc etc etc. buy some mobil and have @ it. change the filter and what not too. its a pain. but if it gets rid of your smell and makes things right, it was worth it.
