You could, but I would stick to 5W-20 for warranty purposes. In the real world, 0W-20 is a 100% acceptable replacement for 5W-20 but that's not the way Ford sees it. Ford said to use 5W-20 so 5W-20 is it.
I don't see why you would need a 0W-20 in your region anyway. I am sure a quality 5W-20 Synthetic Blend or full synthetic oil will do great in your climate.
