Oil Opinions, 5w-40

I am a new diesel owner (2009 6.7) and I want to give my cummins the best possible treatment after purchasing this thing. So with that said I am preparing for an oil change in the future, around 10,000 miles. I noticed in the owners manual it states that I can run 5w-40 synthetic(Amsoil) for all temperature ranges. I live in northern NJ so it doesn't get really hot or really cold but I like the idea of faster oil pressure on cold starts.

Any opinions on running 5w-40 year round?
