I find synthetic to help drop temps a good 10 degrees. Which is not bad. But if your car is new? I recommend nissan esther for the first 5,000 miles then switch to a synthetic. The engine breaks in better with the esther. Me personally, I love castrol edge.
At switch, the car doesn't feel all that great. But once you pushed a tank of gas through it. The engine feels stronger, smoother and I do notice better temps. My Z would see about 240 when pushed hard. With syn oil I would see 220-230 on the reg. I drive aggressive. I live in dallas.
On another note. Just take it to the dealer and let them tell you what they think. Better safe than sorry
