I chose to do my first change (at ~1700 miles) with the Nissan Ester Oil (5W30). I'm probably going to use it again on my next change (planned at about 4K miles) just to help make sure the break-in goes well. My next change after that will be at about 7K (and about every 3K after that, +/- depending on how hard I work the oil), and I'll be switching to a quality synthetic that is known to have the Esters, just to be on the safe side (so far I've heard Mobil 1 Extended Performance and Motul 300V placed in that category, but there are probably others).
That Nissan oil is about $12/qt btw
