Also, during break-in, your car burns oil, so synthetic is not desirable (it doesn't burn well). I actually think this Z just burns some oil as part of normal operation, so I'm going to stick with the Nissan Ester, but I think people with good synthetic will likely be fine.
And: for those excited because their motor hasn't seized up in with ~15K miles - that's not exactly a ringing endorsement of any oil, no matter what it is. You could not change the oil at all and get 15K miles trouble free. Not saying your oil change is wrong, just that that data point is pretty much useless.

Tons of BS in this thread, that's for sure! There is absolutely NO WAY an engine would be run up to redline on the test bench. And the only manufacturer that puts an engine on a dyno at the factory is Porsche. All oil is drained from the engine on the test bench at the factory, after the initial test run. In the case of Nissan for the VQ, it is then refilled with Nissan Ester Oil. Why? Because this engine runs hot, period.
Here's a nice link, read it and stop the madness!
