No Full Synthetic Oil in the Z?

Modshack

We could go on for weeks about this. The only reference to factory fill in the manual is on page 9-5 and says this..

"Your engine was filled with a high quality engine
oil when it was built."

That's not real definitive....

So, again, Nissan highly recommends (can't require, by law) the oil but does not use it themselves for the factory fill, which will be used during the most crucial period (break-in) and which would help limit the number of warranty issues with the engine? Really? Man, that is one dumb company.

The TSB, by the way, states that Nissan Ester oil is required when reflashing the ECU under the TSB procedure for the 3.7 VHR. Isn't the ECU reflash at this point done at the factory?

EDIT: Nissan Technical Service Bulletin ITB08-028a
EDIT: The Owner's Manual was written long before ITB08-028a

Like I said, if you have proof, post it up! I'm sure others would be interested..

Personally I don't care. I ditched my factory fill at 1600 miles when I installed my oil cooler. Pennsoil Dino since then with no differences noted at all. I'll be moving to full synthetic at 5K...

Well I guess you're too busy to read the TSB? I think I posted the name of it at least twice. Go right ahead and use whatever oil you want, geez, I ain't the hallway monitor.

From bobtheoilguy.com:

There is an interesting article by Mike Kojima that goes
into great detail about the Nissan oil. The price is about the same as Redline. Here are a couple of quotes:

"Nissan's special oil and their newly developed hydrogen free DLC coating on cam followers reduces the amount of friction produced by the valve train by a huge amount. This can make a considerable difference in fuel economy, power output and perhaps even heat generation.

What is Nissan's special oil? The oil was developed to complement Nissan's Hydrogen free DLC coating used on the cam followers in the QR25DE engine, the VQ35HR and the VQ37VHR engines. DLC stands for diamond like coating, which is an amorphous layer of carbon crystals with hard smooth properties much like diamond. Most of valve train friction is created by the interface between the cam follower and the cam lobe. DLC is very slippery stuff and Nissan uses it to reduce valvetrain friction to improve fuel economy, reduce emission and increase power.

Nissan, in their search for improving oils frictional properties, figured out a way to substitute ultra hard nano particles for the normal chemical friction modifiers adding some interesting molecular twists. Again due to the convoluted nature of Nissan’s white papers and patents, its hard to guess exactly what the nano particles are but they are definitely an ultra hard industrial abrasive or bearing type ceramic and probably at least in part, nano particles of industrial diamond

Nissans super oil is around 0.5% nano particles by weight. The particles are probably around 10 nanometers in diameter, really very small! A certain percentage of the nano particles have to be carbon based, preferably single crystal synthetic diamond. The carbon content helps make the nano particles attracted to the low hydrogen DLC coating. Instead of making a slippery metallic film on bare metal parts like traditional friction modifiers, the nano particles act like atomic level miniature ball bearings, preventing metal to metal contact and reducing friction to previously unheard of levels. These nano particles are ashless if they find there way into the engine, making the oil low deposit forming for lower emissions. The Nissan super oil does most of its friction reduction in the valvetrain but it still helps in other parts of the engine.
