My belief -- no. There's nothing wrong with the viscosity grade of 5W-30 in most cases (except in the extreme cold), but the big problem with 5W-30 is that it can be formulated with a lot of additives and relatively poor quality base oils. So when you go to a 0W-30 or 0W-20 motor oil, the manufacturer of such oil is essentially forced to use a better quality base-stock that probably will stand up to longer drains, coke less on turbo bearings, or be less volatile creating the dreaded direct injection intake deposits.
5k OCI's are, in some engines, way, way too often, particularly direct injection engines. You're just asking for trouble if you change more frequently than prescribed in such engines, especially if poorer quality oil is used.
