Nissan's factory scheduled maintenance is very conservative. While under warranty I suggest following it. I don't use the most aggressive schedule, just the minimum recommended to be complaint. I personally see no reason to use the Ester oil either (its not required as many have stated).
For our car, it will hit the time limit (6 months) before mileage and that's when I change the oil. I am letting the dealer do this for me (a first in my past 20 years of driving, I have done nearly all of my scheduled maintenance). I choose to run Pennzoil Ultra though honestly a good dino oil would be more then sufficient for this OCI.
After 5 more years and the extended warranty expiration, I likely will go down to once a year changes (6-8K miles) which will be backed by a few used oil analysis reports. No sense in wasting resources.
