I got a little white haze on the oil level window that refused to go away but the oil seemed fine. That haze is usually indicative of some condensation in the oil, often goes away with a good long run that heats the oil and boils all the water out. Mine seemed to stay no matter what I did.
For whatever reason a lot of the Ducati's fog up their oil level window, so I don't think it's the choice of oil that does it. Now, living in the Pacific Northwest, well that probably doesn't help
