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

:wtf2:

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...

is the dueling over?

:icon17:...I doubt it...You know all about the "assume" thing....:tup:

What does oil have to do with the ECU recalibration?

I just looked good and hard at your Avatar.......ROFLMAO!!!!!!

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. :tup:

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.

these types of topics, are always going to have controversy and in the end what's the answer? that depends who your listening to....it's like asking what's the best car under 50k? right!

with Steve's Proof! can we call it a day?

Nope...Says nothing about the current factory fill. The TSB was to solve an early problem, since rectified. The controversy continues!

http://images105.fotki.com/v443/phot...227/gun-vi.gif

I doubt it, Trip. You know all about the "assume" thing :tup:

Wow. OK, we'll agree to disagree. Nissan developed it's own oil specifically for this engine, but they don't use it. Sounds reasonable.

"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."

OK everyone, lets stop arguing, 370zSteve is totally and 100% correct.

Lets all make a future effort to never disagree with 370zSteve, as he's proven us all wrong, and while our facts and opinions may be correct in the real world, on the internet, 370zSteve is king, and makes all the rules, and is never, NEVER, NEVER wrong.



-----------

As for the requirement Nissan includes in the ECU Reprogramming bulletin - perhaps it's so that Nissan can't fault the tech for incorectly flashing the ECU. It has nothing to do with the ECU, it has everything to do with Nissan covering all the bases, as they tend to do, to ensure that things are done very specifically and in a very controlled way. Nissan has tested their proceedure by having the engine loaded with thier brand of oil. Not hard to imagine. They make it a requirement because that's what they know is in the engine in the conditions that they tested with, and know that to produce successful results.

Now, the real question for the bulletin is this - why reprogram/flash the ECU to correct the VVEL system making a tapping noise....not why did they use Nissan brand oil...
