Nissan ester oil showed up when the VQ37VHR engine did in the G37 and 370Z, IIRC. It came as the recommended oil for that motor because of the tighter valvetrain clearances that came with the VHR motors. I used Redline in my 370Z because it was an ester-based oil that was also a synthetic - the Nissan ester is not a synthetic.
With my QR25, VQ35, and my VK56 motors, I just use Mobil-1 extended performance. I have around 300,000 miles of proven use there, and I can buy it at Wal-Mart and not get railed on pricing.
