No Full Synthetic Oil in the Z?

So you are saying that Nissan recommends it's Ester Oil but does not use it? Seriously? Talk about gum-flapping! Do you know anything about the VVEL tapping issue? Nissan started using Ester oil in the VQ engine in the G37 (they also re-calibrated the ecu) because of it. The TSB is ITB08-028a. Wasn't hard to locate on the internet.
