Ok, now listen to me. You could use non-API oil, and you probably won't have a warranty claim for an engine problem. I suspect if you don't change your oil at all, and just keep it topped off, that you'll make it past the warranty without a failure.
The question is what is the best "preventative" maintenance in the long-term? They're telling you doing the bare minimum changes with API is good. Doing more frequent changes with their oil is better.
Does it matter? Maybe depends on how long you want to keep the car.

Ok, I listened. Now kindly listen to this: It's not magic, and it won't make 500k miles. But there's likely a difference. 150k miles versus 200k miles before valvetrain failure with the friction modifier? I don't know. But their engineers spec'ed it for a reason.

Publish what? Why? They don't care how you maintain your car after warranty. That's your business.
In fact, I'm think they would rather
not publicize that their engine should have special oil...because it might turn some people off. It could be the engineers fought to get this in the manual for people smart enough to heed it. Maybe not. Who knows.

Engineers don't care about marketing oil. But I bet they're interested in making their tricked out valvetrain last. And I doubt Nissan cares about getting into the oil business.
I mean, it's kind of like the argument for using synthetic. Will your Corvette engine fail in the warranty period if you don't? No. But it's preventative. And there's not even anything so tricky on the Corvette engine, as there is on this engine. So the "nanoparticles" combined with this tricked-out engine gives me pause.

Thanks, man...I appreciate your permission.
