That's my own rule, but let's not muddy the water. They have said, in terms of maintenance, that their oil spec is better. I mean, do you think they added a friction modifier to this oil for no reason?

The only technical reason I've ever seen from Nissan regarding the use of their ester oil is that in some 370Z engines valvetrain noise may be reduced with use of the ester oil - and reduced valvetrain noise does not equate to longer engine life.
In my world noise means wear - especially in valvetrains.

They have done neither.
This engine hasn't been out long enough to have a bunch of owners over 100k miles, has it? And reducing friction in their high stress valvetrain does not equate to extending life in all engines.

It's in the maintenance section saying it's the recommended lubricant...you think it's there because it has no effect on maintenance of the engine?

I don't know that they're making much money on a $12 quart of oil that nobody's buying. The markup on their parts is way higher than that, percentage wise.
