Default Use the Nissan recommended Ester

Esters provide better lubrication because they are "magnetically" attracted to each other (molecules) and to the metalic surfaces in the engine.

Motul has some great info about esters

Essentially what the article says is that normal oil will only protect metal to metal contact while the engine is running. Ester oil, because of it's attraction to the metal surface, will continue to create a film on the metalic surfaces even when the engine is not running.

So in addition to it's ability to be "custom tailored" it prevents excessive start-up wear (this is usually where most of the engine wear comes into play).

As part of the perks my dealership offers at no cost is a lifetime engine/transmission warranty and oil changes for life at $19.99 using the Esther oil which is designed for the 3.7 engine.
