If you are seeing high temps constantly switch to a 40 grade.
You can see in the chart that a 30 grade oil at 212f has the same viscosity as a 40 grade oil at 240f. Those these only come in 10w40 commonly so you will lose some efficiency for cold starts because the oil will be thicker then a 5W.

Mobil 1 makes a 0W-40. It's their European blend. And it only costs $25 for 5 qts at Walmart. I know a number of forum members are running it. I was considering it because the Z runs quite warm. I may try it for my next oil change to run through the summer. We'll see.
