This post reinforced the "ignorance is bliss".......I'm sure you got this definitive information from the Ranger and Tahoe forums.....Carry on!

God this topic is beaten to death.

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.

You're right VCuomo; as long as you use a good quality oil filter and follow the Manufacturer's instructions on the miles/months time-frame for changing it, all should be O.K. The advantages of the synth' oil are the extended intervals between changes and high-temp' shearing protection. Some people actually prefer regular dino' oil. I try to baby her, but not to extremes; these cars are very reliable, engine-wise.

And just what are your qualifications.

I'll say it again:

Steve: You only quote from bobtheoilguy, yet you make no point. You were successful at adding to the length of this thread, but you added no new info. Why did you post? Greg

Mod: I will resist the temptation to suggest that my posts are "over your head." This site exists to help other Z owners. Your acerbic comments do not support my belief. Maybe I am mistaken. Please copy/paste my comments from the Ranger and Tahoe sites to which you refer, and let the other Z members decide. R/S Greg

[QUOTE=VCuomo;285795]And just what are your qualifications?QUOTE]I'll key a public telephone number on this site's PM, you call me, then I'll tell you. Or we can meet face to face. Unless you are a chemist with focus on petroleum refining, you are way out of your league. You want to play hardball? BRING IT!

Anyone who wants to follow this advice, please do so. Please update this site with the results. Also, please ID the oil and filter manufacturer, the viscosity, the date, and mileage of each oil/filter change.

Zless, might I suggest you head over to the Tahoe forums, because your schitty attitude really isn't welcome here. :tiphat:

[QUOTE=Zless@arizona;286612]Wow, what a douche. :shakes head:

see if you can get him to take avitech with him :roflpuke2:

I love oil threads, so very much.

Hmm....so what's the underlying logic here? That unless someone is an expert in a certain field, they're not entitled to question another individual's credentials in said field? Seems a little silly, don't you think? I mean, he's just asking what your qualifications are; he's not challenging them. Under your logic, if some guy expresses an opinion on, say, health care reform, nobody is entitled to ask him what his qualifications are unless they themselves work in the medical field with a focus on health care law. Or if some guy takes a position on troop levels in Afghanistan, nobody is entitled to inquire as to what his qualifications are unless they happen to be a West Point graduate with a degree in military strategy, right? Because you know, that would be completely uncalled for; it'd be playing hardball, in your words. It'd be grounds for a face to face throwdown! :rolleyes:
