I feel if Nissan is supposedly ahead of the engine design curve then such an ester precautions would not be necessary and the Nissan stated API rating should suffice as this is a mass produced vehicle for the masses to be serviced by standard dealerships and not some esoteric engineering prowess to be serviced by the few who have the qualified fluids to do so. That defeats the premise of the Z from its very origins. Hey, but that's just me.

SoCal,
While it is true that there is no mention of Nissan Ester Oil on page 9-5 of the Owner's Manual, I just want to point out that this is on page 9-2 of the Owners Manual:
So while I agree with you that owners are not expected to purchase a Service Manual, one doesn't actually have to go to the Service Manual to find a reference to this oil. But in any case, it is indeed just a recommendation, not a requirement, so I also agree with you that any oil that meets or exceeds the stated API rating on page 9-5 should suffice.
