I'm aware that if the oil is a Xw30 it's compatible with the engine. But, it'll cause more wear to have a 10w30 than 5w30 or 0w30 in theory - If the car engine can take it and not leak or burn oil, is there any reason to not use 0w30? I imagine it would make starts - Summer or winter - easier and get to lubricating the system quicker.
