I used the 0w-40 for quite some time in the Texas summer and "winters" with no issues. including on the track. Due to track usage, I switched a while back full time to 5w-50 or even the 15w-50. No issues with those. But I don't daily the car either.
fwiw

edit: if you have any warranty, you might want to stick with the 0w-40 factory recommendation. Some might say it doesn't matter, but if you have issues, it can't hurt to be using their recommended oil if there is a problem.
