I always bring my own oil in for oil changes. The dealers will put in garbage oil. I run Redline 5W40. It's a little more pricey but it is top notch. I live in Vegas where it is 110 degrees outside and Nissan VQ engines like 40 weight oil for more protection. It is an ester based synthetic. 20 weight is too thin, especially in the hot summer weather. No wonder your temps are higher.
