No Full Synthetic Oil in the Z?

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.
