370z requires premium fuel?

Also, the owners' manual for the 350z warns you that you should only use 95octane if you really have to - is this the same for the 370z?

Personally, I wouldn't use anything but super unleaded and I assume it's the same for the 370z.

In addition, I assume that the ECU will adjust itself to account for different fuel types, as I believe it does in the 350z.
