No it won't. At warmer temperatures there is no guarantee a 0W-rated oil will be thinner than any other rated oil. It may well be thicker.
Besides, what does flow get you?
I guess I really know nothing about oil at 46 yrs old. I was under the impression that a 10w and 5w are the same oil during summer and only different below freezing. At least I hope so, because I've been using 10-30 in a 5-30 application during the summer. Now I fear I'm causing damage.
