2012s on lots....where are the oil coolers?

Sibze

Is this real life?

Pharmacist

So where do these enigmatic nanoparticles fit into all of this? I was under the impression that nissan's oil is unique due to those nanoparticles and not the esters since there are already several brands of synthetic ester oils on the market.

^ you are posting (mis) information with no source. Burden is on you to source, not me to disprove.

if four articles detailing the effects of the ester compound in conjunction with the h free dlc don't at least pull back the curtain for you, reading 20, 40, even 100 arctiles telling you the same results won't do anything either.

This isn't a pissing contest. A person either understands the fundamentals behind the science or doesn't. From there its a matter of either agreeing or disagreeing with the findings.

Cool off buddy, its just science

We all get science, none of us are morons here, and quite a few of us have engineering and scientific backgrounds. The reason he's getting miffed is because you're out here touting your credentials as giving you some magic understanding that mere mortals cannot hope to achieve about this subject.

If there's a reason that running Nissan's specific ester oil blend is better for the friction properties of the VVEL heads than other quality synthetic ester-blend lubricants, we'd love to hear about it. Nissan's basic science work that we've seen in the PDFs combined with available data from oil mfgs don't even begin to answer that question in a rigorous manner, in either direction. Empirically though, nobody's gone and shown a dyno power dropoff from switching off of Nissan Ester either.

To expound on the science part: what they show in the paper is that (a) their nifty H-free DLC does better than two other types of surface material regardless of the oil type used (b) their PAO + ester blend does better than regular oil regardless of the surface type, and (c) (DUH) the best results in the test come from combining the two best-tested: their PAO + ester and their H-free DLC.

What the paper does not at all address for our pragmatic needs: (1) Is their PAO + 1% glycerol mono-oleate the *only* variety of engine lubricant that can reach frictions levels this low or lower in combination with their H-free DLC? (2) More specifically, was it really exactly 1% glycerol mono-oleate that works, or do other percentages of other similar esters work? (3) Is glycerol mono-oleate, or another equal-performing ester in tests with H-free DLC, a commonly used ester in ester-blended oils from other manufacturers?

You get the idea. Unless Nissan and/or other oil manufacturers want to take their science (and engineering) reporting to the next level and answer the Practical Questions That Matter To Us, we have to rely on empirical data from running these engines in the real world with various oils, which so far does not fall in favor of Nissan Ester Oil.

Bingo. Tons of bright, technical people on here.
No need to be condescending to the group....

Right, but I'm not endorsing their results, rather I was willing to provide a venue to see the published results of the studies where a technology that was commercialized specifically for the engine in our cars...and I suppose, to a degree, my interpretation of the findings.

The questions you seek answers too go beyond what would typically be published...ever. The answers are proprietary, and are outside the scope of the experiment, which was to determine the effect of a particular friction modifier compared to other conditions.

I understand your questions, but they are far "downstream" from this type of research in the whole scheme of R&D. They fit in as a way that further develops an existing technology, finding the best, perfect combination. The research described in the papers is how technology emerges, these proof of concept experiments. A scientist finds a probable breakthrough, either through theory or pure accident, sees the potential and conducts an experiment to prove the concept.

You have to understand the type of research it is, and I genuinely don't mean that in any condescending way. It's framing the issue in order to see the meaning in its results. If you are expecting to be able find the recipe for a perfect oil mixture, or hoping to see a comparison of brands of oil in the VQ37, or the effects of > 1% or < 1% you will be sorely disappointed.

Exactly what I said from the start. Scientifically interesting, not yet practical

Davey

Hey! I happen to be a moron, you insensitive clod!

toxik

I get it... its an oil cooler thread. I suggest cooling off by air and by water Dan.

Or determining that the test method wasn't arranged to make a notable determination (which anyone in other engineering discipline can recognize). Maybe mech focuses less on that stuff....I dunno.

The easiest way to find if research is significant is checking for follow up. I don't see much.

I see in the description that the 2012's suspension is stated to be refined, this has led me to think the 2012 370Z will include everything the 2011 European GT Edition has received including the oil cooler. I hope they improved the paint quality too. I'm hoping they improved the paint quality, even though i'm a detailing fanatic i still wouldn't mind a better quality factory paint, which shouldn't be something i have to ask for. I'm getting a clearbra as soon as i'm done detailing her once i take delivery, but still a durable paint job should be included.

Brake ducting? Factory oil cooler? Refined suspension?

Why am I getting the feeling that I should have kept my 350Z for another year...

I think I'm going to just get a moped or something.
