Engine noise issue with my 2008 G37S

[Tampa G35 Sedan 6MT]

correct me if I'm wrong, but I think Toyota designed a motor with Yamaha, for the Celica GTS. It was a 1.8L I-4 with 180hp and it had VVEL....

Why did those cars not have the same problem if it is from the VVEL... as well as they didn't need the ester oil!

[SteveTheTech]

VVEL from Nissan

Here is the breakdown of what the system actually does and how it works.

[Tampa G35 Sedan 6MT]

That is really good info steve... I now understand how it could be more efficient by using vvel!

For the nissan GTR it is a 0W-40 mobil 1 only, if any other oil is used in that car BYE BYE warranty. So the oil in the 3.7l is definatly differant than the oil in the GTR. This is not a case of whats good for the goose is good for the gander.

The GTR was designed with that oil in mind kind of like the 3.7hr was designed with ester oil in mind.

I don't know that is true. The ester oil "creation" date, according to the Euro patent application, is in 2006. Before the 3.7 was released. If the 3.7 or VVEL absolutely required this oil, it should have been factory fill.

For more, see below.

Quote »I spoke with a fluid engineer about this matter and this is a direct quote from him "motul is motorcycle oil, its NOT THE SAME" Nissan Ester Oil is definatly differant it is patented (as you can see) and it will not be sold in another box/bottle until the patent is up obviously the onlyway your getting it is through nissan/infiniti with the part # 999MP-5W30EP [/quote]According to the Euro patent application, the oil is not yet patented. A Euro patent application has been filed. No Euro patent is even currently pending.

The patent application describes an oil which improves fuel economy by, essentially, being more "slippery" due to use of metallic oxide and carbide molecules in different sizes than contained in conventional oil to reduce the "sticking" to parts and to improve the "slipperyness" of the oil. All comparisons in the comparison chart are to PAO based oils, which would mean conventional or groups 2 or 3 synthetic oils. No comparisons are being made to groups 4 or 5 synthetic oils.

The claim is to improve fuel economy by improving the ability of the oil to lubricate over conventional oils. My first thought was, sounds like the claims of synthetic oils. If so, why not just use a synthetic oil. If really so, I wonder if groups 4 or 5 synthetics are even "better" than Nissan Ester oil?

funny you should mention that i won't say it is or isn't but keep what you just said in mind and its not just the 3.7

[zozoka1212]

Steve, Notalk thanks.

It clears it.

So what the 3.7 filled from the factory with ester oil?

[fbpem1]

the 3.7 filled from the factory with ester oil.

fixed

[Tampa G35 Sedan 6MT]

fixed

That means that when they get to the dealers the oil is changed to ester?

[fbpem1]

no i took the question mark and the so that means out of your post and posted fix with turned it into a statement meaning the 3.7 and the 5.0 are filled from the plant with Ester oil Maxima 3.5 as well.

[G_whizz]

Guys...let's keep this thread on track and drop the name calling.



I am here watching... just playing Net Ninja..

[Tampa G35 Sedan 6MT]

so even the Maxima has to pay for the ester oil? It would be funny to see the look on their face when they buy a 25k dollar car and then get a $100+ bill for an oil change.

i would go look at a new maxima price tag. they are extremly nice. and a nissan ester oil change next door is 80bucks no more than a full sythetic oil change at a dealer.

Synthetic lasts at least 10000 miles though - does ester?

[fbpem1]

dosn't matter how long its claimed ot last infiniti's stand is 3750 regardless of what oil is used.

[Jacko3]

I am still wondering why Nissan feels a need to use this Ester based oil. This is really intriguing and in some ways troubling especially with the new maxima that probably has the VQ35DE engine, or does it have the VQ35HR engine?

[Jacko3]

Marlin and Fbpem1:

If God did not create that oil in some far away place up in the sky, my holy grail is 3000 miles or less for every oil change---regardless of what oil I use, given how hard I drive my car. Nissan or whoever makes the oil is preaching to a rebeliious choir boy here (Jacko), with there 3750 or 10,000 mile oil change intervals. Don't even try or attempt to change my mind on my precious 3,000 mile dogma because it will just be like pulling teeth---won't work. The fresher the oil, the healthier the engine.

Haha, naturally Jacko - the fresher the better for anything I was mearly saying that Nissan/Infiniti recommends a 3750 cycle for conventional oils. Synthetics are designed to go longer...

I actually had an interesting convo with my service manager - they're stand is that you have to at maximum change the oil (conventional) every 7500 or 6 months, or else your warranty is jepordized. He also said that 10000 on synthetic would be warranty covered...

in a perfect world sure, but motors use oil its a fact of life no motor is perfect and they all use dosn't matter where how or when it just happens.

lets take for instance your run of the mill 06 G35 Coupe, 6 speed, with the tsb already done. That motor will use oil not a design flaw just a fact of life and how the motor is built loose and how its kind of on edge being a very effeicent motor.

Another example would be a factory turbo car, they are going to use oil dosn't matter how much or how little fact is they use it, my car does use oil a small amount just about the right amount for me to feel comfordable and not go over 3,750 miles.

Granted the intervals are there as a recommendation but ask that same service manager when you have a blown motor and he and infiniti are going to be wondering why you didn't change your oil at least every ~4k miles.

7k+ is pushing it in my opinion on anything dosn't matter what it is. It starts getting into my head on my personal cars at about 2500 miles, at normally get them done at 3k but i will be lazy and go right to 3,750 sometimes.

Like i said yes it is personal preferance but i would rather be safe than sorry, since its not actually the breakdown i'm worried about its about the fact that any kind of performance motor will use oil. Kind of went long winded to say all that but oh well i'm bored and have to be here late.

Well said! You are true son of NicoClub. Keep the good words coming. We learnt a lot from you all today. Have a on me.

Well said! Well done. I have been saying this for a while, and thinking it forever---the G-35 engine and manual transmission was built so loosely that floging the car routinely can literally never lead to what most might consider abuse or break down. And this probably explains all the rattles when it is cold and funny behavior of the car in many instances. As the car gets warmer or heat soaked, it becomes almost silent and quiet. I am in true awe of this Nissan design philosophy--that is sports car design philosophy, especially if one intends to go out there an flog the car. Thanks for confirming another of my convictions and thoughts about the car. I know when I say these things on these threads, many beocme skeptical. I am highly connected to the car in ways that even surprises me

[SteveTheTech]

I'm going to take this discussion page a a few pages and some good ole bickering. Stupid needing to work and missing arguing with internet strangers.

I don't know that is true. The ester oil "creation" date, according to the Euro patent application, is in 2006. Before the 3.7 was released. If the 3.7 or VVEL absolutely required this oil, it should have been factory fill.

How long do you think it would take to develop the VVEL technology? It is not an over night product. Something that took years of work from many very people like designing an intake system that meets the needs and requirements of the new G and the federal government.

As Fbpem1 said they are filled with it when they come off the line in Japan. I guess they assumed we would just use the right oil.

The Maxima I find interesting I do not know the specifics I stay away Nissans. For the most part the technology and theory are similar but the engines and power train systems are slightly different. I will have to check into this.

There are oils on the market that claim all kinds of things. There are some oils out there that claim you can drive your car 15K w/o an oil change. I don't know what car I would actually want to try this in but no one I know would consider something like that. At the end of the day though it is still just a recommendation and if you believe in the product go for it.

Being the life blood of the car I would chance it I would want only the best for my car. I am starting to believe that it is less about price and more than the company informing owners that there car needs something special.

What about the diesels that require urea refilling. The Nissan also requires special transmission fluid, and hold on this is a big one.... Premium...

[zozoka1212]

BMW does that. No oil change for 10-15k not sure. If I won't forget I take a picture of my oil. I have now 2k on the car and it is dirty. I have an apointment for oil change on Friday.

I can't see myself runninga same oil for10k. Especially if the car is turbod.

Zozo

[SteveTheTech]

I really wish more people had the same out look toward their cars as you do zozo. But really though you are more than 1600km till your next service. Is that only 2,000 mi on the car? For a first oil change that is a good idea.

Just having a comprehensive inspection every few months is just a good idea to keep on top of what the current status of key systems and wearable items such as tires and brakes.

[zozoka1212]

Yeap only 2k on the car and on Friday she'll be lubricated with new oil. I only go for the oilchange this time and the scheduled 6000 km service wouldbe around when I hit 6k. I'll have another oilchange that time and then just keep the schedule from that point.

I think we all do check the cars often. Reason because we love cars.

I do it with my wife. She does hers and I do mine. She checks all the fluids and pressure check the blades,etc. It wasn't hard to show her stuff. She's got 2 brothers. Both of them hands on guys. Hell back 10 years ago she helped me swap engine in my fun car. She knows the name of all the tools. It is kind of handy when you are in a tight spot and you just tell her what you need and she is there with it in seconds withthe right tool. I had sometimes I could not fitt my arm in the place she's like I do it, I do it.

But there is a price for it. We do everything together. Include cleaning the house. Not my favorite but I do it with her and my son. My son cleanes his rooms. My wife and I do the rest.

[Sentientbydesign]

I don't appreciated your comments in the least bit. Sentient By Design is quite easy to spell btw.

My mention of Steve's lack of qualification to say what he did was basically to tell him to watch what he states to be true. You techs are regarded as being more knowledgeable than the rest of us. Steve comes in here saying that Motul is not API certified

It's one of the few API group V oil manufacturers. To my knowledge, that is some of the highest quality synthetic you can find.

Motul may have started out as a motorcycle lube, but they make a huge assortments of oils for passenger vehicles and more. Not sure what your fluid dynamics friend was trying to say, but I don't think all of the facts are there.

If you want to discuss my product, please start another thread. That type of discussion doesn't belong in here.

One thing I want everybody to be clear about. I'm not sure what it is about the G37's VVEL design that is causing problems. Hell, I don't even own a G37. My point in all of this is that Motul is an Ester based synthetic. And it is API approved as an engine lubricant. It's also half the price of this specially Nissan oil whose capabilities are still unknown.

[Sentientbydesign]

I know that the Inifiniti Techs are taught to regard everything from the FSM as being gold, but realistically, engineers are people too. They can make faulty designs too. A perfect example is how the rear coupe rims got larger in 2006 to combat uneven tire wear issues on the rears.

Those of you who believe that oil needs to be changed every 3000 miles are lying to yourselves. If you push the engine hard enough, your oil may not even last that long. But on the flip side, your oil may be fully capable of lasting 7k, 10k, or more.

Without an oil analysis by a reputable lab, you won't know. Most maintenance intervals take into consideration the lowest common denomenator. For any of you with statistical background, you'll know that the LCM is rarely if ever the average and even less likely to be the optimal value.

[Jacko3]

Hey guys:

Check this link out. http://www.performanceoilnews....shtml

It seems like for racing and extreme perfromance Royal Purple and Mobil 0W-40 which the GTR uses, are great. But for regular applications, other oils in that test seem to be great. And check the horsepower data of the Royal Purple and Mobil 0W-40 at different RPMS Kind of like what I said in my previous RP write up.

[fbpem1]

which why TSB's and Recalls are issued.

industry standard is industry standard correct? why go against the law of averages. sure an oil may last thermal and molecular breakdown till 6k another may do it at 2.5k lets cut it in the middle at 3. Which is really not what i'm talking about i'm mainly talking about with the 3,750 miles not from oil break down but from the simple fact performance cars USE OIL always have always will.

My old sfwd car i changes the oil at probably 3 miles which is on average 12 passes.

Street cars of mine depending on level of power i'm throwing at it will get changed at 1.5k or 3k current vehicles have been 3k and i have had no problems with it at all.

Although i have had 1 car i didn't car about that wouldn't quite running 48,000 miles no oil change

[SteveTheTech]

I knew you would read that and get your short and curleys in a knot. Yes I agree that your googling skills and ability to read mdsds and the such are superior to all. Knock the factory training and propriatary information Fbpem and I are privy to if you must and substitute your own notions I do not care. When you buy a 37 and face the decision on what to use go for the Motul hell I don't care put F*ing crisco in there I know it fries my chicken well without sticking to the pan.

The facts have been layed out here there is a plethera of knowledge on this thread alone concerning the benefits of ester for the OP, and other owners to make an educated decision. I have shown the chemical benefits of this product which I believe in as something that will not only be used in this car but more likely that not in almost all of the upcoming vehicles.
