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...

ALLRIGHT! we agree to disagree! I agree

And the trolls surface out of the slime..............I guess that's what I get for posting the info, as requested. Now back to our regular programming.

:bowrofl::roflpuke2:

Sorry, not a troll, perhaps you're new to the internet?

IN fact, here's a piece of advice...

I'm more than done with this thread...

:iagree:....X2

X3

Move on folks!

kannibul: Excellent points! Most important to me is that you mentioned Group III/IV/V oils, and that is the crux of the matter!
.....IIRC, G-III is the "hydro-cracked" oils; G-IV is PAO (polyalfaolefin) oils; G-V is the ester oils.
.....the G-III oils are the ones that Castrol uses, and is allowed to call it "Synthetic" due to a lawsuit. G-III oils are processed from petroleum-base stocks and are not "Synthetic" as the industry and scientists who created synthetics understand the term. I do not use Castrol G-III oils because they lied and used attorneys and judges to be able to label G-III oil as synthetic.
.....In the early 80s, I started using Mobil1. I copied a test run by Ford that I included for my thesis: New oil filter and Mobil1 oil change; keep in vehicle for 100,000 miles (include 15,000 mile filter changes and oil top off but no drain); Arizona 1977 280-Z. The Ford engineer examined the engine after the 100,000 Michigan Winter/Summer miles and it's specs were within factory new! No issues with my inline-6!
.....G-IV ester oils are mainly used in racing vehicles. The predominant race-only use is due to two characteristics unique to esters: they do not last long, and they absorb water. Race use heats the engine and oil so that the water evaporates--driving your 370Z to work may not reach the oil temperature necessary to remove water.
.....Nissan's recommendation to use their proprietary ester blend probably solves the water retention issue, and provides the optimum lubrication for their variable-valve system.
.....Corvette crankcases are filled at the factory with Mobil1 and have a 15,000 mile drain interval. I was a test driver and prototype development technician for GM, and we only used Mobil1 for the Corvette engines for top off and changes. The engines are/were run for a million miles basically non-stop 24/7, then disassembled and inspected.
.....There's a reason GM and Nissan recommend certain oils for the high-end engines. The VQ37VHR is not a Chevrolet 350 c.i. V-8 with hydraulic actuated pushrod valves, and one should not use the same oil for both engines.
.....Some 370Z owners on this site are switching to Motul which is mostly an ester-based oil. My concern is the buildup of water in the crankcase if the outings don't include at least one hour each day of redline racing on the local track.
......I can almost guarantee that using the Nissan Ester blend will be the best choice. I can not state that using a different synthetic will harm your engine--only the experience and reports of the 370Z members will identify issues. I will recommend staying away from conventional petroleum-based oils for the VQ37VHR.

R/S, Greg

nice informative response greg :tup:

i was trying to get motul ester based synthetic here in my area and to no avail...

i ended up getting nissan ester from my local dealership...parts manager gave me a discount on it so i was happy and ill probably just stick with it..or atleast until more info is compiled and the availability of syn esters becomes more prevalent in my area...

Thank you, sir! You all are looking for answers for your Zs; my goal is to share what I know if it helps you--no B.S.! It is my honor to have helped Travis with his dedicated race-Z.
.....kdo2milger, look at RedLine oils. Their stuff is also ester-based. See if they have a blend so that the water-issue is covered. You can order online! R/S, Greg

ya, it was between redline and motul...i just couldnt justify shipping cost...thats why i was hunting locally...

i even had oriellys auto parts call their regional manager here and try to get motul and redline oils added to their store lineup...no can do at this time they say...

ill stick with nissan ester for now...:tup:

i feel the love in here!

mobil 1 for me. keeps it easy :p

Girls, girls, girls.....When was the last time you heard of an enfgine failure that was definitively caused by oil issues??......I'm guessing NEVER.,..Put whatever you want in the car...Chances are a few years from now you won't own it anyway..

Actually, that just might end the thread right there! :iagree:

We agree to agree....:tup:

Sticky this reply. LOL!

:driving:

:rofl2:

Sorry, but this isn't true... I had 2 Rx8 in the last 4 years whom both ran on Grade V synthetic oil (Royal Purple) without any kind of issues. However, rotary engine (and their ?&*" catalytic systems) canno't burn all types of synthetic oil (ex. Mobil 1 isnt made for rotarys due to additives)....

Re: "...(sic) enfgine failure..." The last time I was contacted to help with an engine failure was due to a stalled engine. I checked the oil level and found none on the dipstick. Attempts to rotate the crankshaft failed--the engine had seized due to no oil pressure/lubrication==>>it was a Toyota 2TC--as indestructible an engine ever built--the owner was, literally, handicapped, and should not have been driving the vehicle.
.....Re: "...put Whatever in the (sic) car..."; I have a Saturn I want to sell only to you, Modshack. I drained the oil and coolant, forced dirt into the oil fill port, put a brick on the accelerator pedal, and ran the engine bouncing off of the limiter for several minutes. The engine did not seize. We had to shut it down because we had to return to work (Saturn testing facility in North America ;-)
.....Maybe your "...put whatever you want in the car..." is correct and accurate and valid ;-) Personally, I use dirt! The car mentioned above was crushed. Greg

Modshack's comment clearly was intended to persuade people to fill their cars with dirt instead of synthetic oil....

:ughdance:

I use 1% milk

Well he said oil issues, not lack of oil issues. :icon17:

Yeah...I fail to see the relevance of the comments from Arizona.....Perhaps he is confused.....:shakes head:...or trying to make a joke? Hard to tell...

Dude, :hello: just having some fun while truthfully addressing the points you made in your original post! You do request to be entertained. I'm not confused. Cheers! <insert 2 beer mug smilies>
