I have read plenty on Mocal products, and have been using them for years. Oil like all fluids will take the path of least resistance. If you prick your garden hose with a push pin and then turn it on, you won't see much of any flow out of it. 99% will be coming out the large open end. This is going to be the same effect. I really doubt the small amount of oil going through the cooler is going to make a noticeable effect. Even with an overly large cooler.
If you are really concerned with this then i would suggest using the factory "coolant collar" that is used on some of the colder climate G37s. That would allow the coolant to help bring the oil up to temp quicker, as well as maintain more consistent temps.
