I am in the Phoenix area and wonder if 0w40 might be a little light for the extreme heat here, and add to the mix the amount of heat the condenser creates under these conditions. I will say that the temp gauge stays right on center when running in the summer. Would any of you consider maybe 5w40?

I'm in Georgia and I use 5W50 but only in summer.
I have 0W40 in there now, as 5W50 is damn thick in the cold - as testified to by my oil pressure gauge.
