You may be right but when I looked at the data sheet on it I don't recall any specific mention of ester additives. If it's part of the formulation, Castrol apparently doesn't think it's a feature worth touting.

has anyone heard anything on how long between oil changes with Ester oil
Dealer told me you can almost double the mileage, but nothing official from Nissan.

If you're using the oil that's recommended in the Owner's Manual (which is what Nissan Ester oil is), then I think it'd make sense to follow the service intervals in said Owner's Manual.

So this topic is bugging the crap out of me.

Anybody care to clarify... but if an oil is a group V, it contains esters? The question then becomes, how much of the oil is esters. Correct?

EDIT: Ok I think I answered my own question. It appears group V doesn't mean it necessarily contains esters, but it groups all oils that don't fit into the first 4 groups. It is that esters are grouped into group V oils.

EDIT 2: Would switching to a heavier weight oil have a similar if not the same effect as using a lighter weight, ester oil?

EDIT 3: Looks like Royal Purple's Synerlec technology resembles the benefits of an ester oil. Whether it is an ester, I have no clue. Check it out: http://www.royalpurple.com/synerlec-oil-additive.html

An oil company is not going to give away their formulation, but they will answer your question of whether they use esters or not.

I've been conversing with a company called "Amsoil" here in Canada about this very issue. Here's what they told me this week:

Dear ****,

I checked with our tech dept.

The oils that meet and exceed Nissan specification is made with PAO (polyalphaolefin) base stocks.

Ester based oils perform better when compared with conventional lubricants. While PAO has significant advantage and performance over ester based oils.

AMSOIL does make ester based oils but they are recommended to industrial application like compressor oils.

Using the recommended AMSOIL will not void Nissan warranty since AMSOIL meets and exceeds the specification and performance standards set by Nissan for the 2009 370Z with VQ37VHR engine

AMSOIL also allows the convenience of stocking one product for a wide variety of application / models.

Now, I don't know whether Amsoil is available in the USA. But, I will be giving it a try when my first oil change is due. I'll keep you posted.

Here's a link to the oil they recommend: http://wboil.com/amsoil/5w30-synthet...r-oil-asl.html

Found this from another forum:

Quote:

Quoted from Duluth Diesel in TundraSolutions Forum.

Tundra Solutions Forum - View Single Post - First oil change in 3 hours

"Not all synthetic oils are the same. Mobile is a Group III synthetic, not a Group IV. Even though the label might say Full Synthetic, it doesn't mean the same thing for all oils. As for extended drain intervals, it is fine to run extended drain intervals with a Group IV synthetic oil if you couple it with better filtration. Not all oil filters are created equal either. Fram and other cheap oil filters don't filter much below 35 micron and are just cellulose (paper based) filters. Higher quality oil filters have synthetic media, not paper, and filter much better. AMSOIL Eao oil filters filter down to 15 micron, and their bypass filtration systems filter down to 2 micron at 98% efficiency.

There are many oils out there that call themselves synthetic, but not all are created equal, and that's important to know. You do get what you pay for. Group III synthetic oils only use about 12% synthetic base stocks. The rest is hyrdocracked petroleum base stocks. For major oil companies who have their money in crude oil refining, the word "synthetic" is merely a marketing term. It does not mean 100%, but just that a percentage of synthetic base stock goes into their product.

The oils that are commonly mentioned are Group II and Group III synthetics with the exception of Royal Purple, which is a Group V. AMSOIL is a Group IV synthetic (PAO) but also uses Group V Ester technology. It gives you the best of Group IV and Group V synthetics. Mobil 1 is a Group III synthetic. AMSOIL is a Group IV synthetic.

In the late 1990s, Castrol started selling an oil made from Group III base oil and called it SynTec Full Synthetic. Mobil sued Castrol, asserting that this oil was not synthetic, but simply a highly refined petroleum oil, and therefore it was false advertising to call it synthetic. In 1999, Mobil lost their lawsuit. It was decided that the word "synthetic" was a marketing term and referred to properties, not to production methods or ingredients. Castrol continues to make SynTec out of Group III base oils, that is highly purified mineral oil with most all of the cockroach bits removed.

Shortly after Mobil lost their lawsuit, most oil companies started reformulating their synthetic oils to use Group III base stocks instead of PAOs or diester stocks as their primary component. Most of the "synthetic oil" you can buy today is actually mostly made of this highly-distilled and purified dino-juice called Group III oil. Group III base oils cost about half as much as the synthetics. By using a blend of mostly Group III oils and a smaller amount of "true" synthetics, the oil companies can produce a product that has some of the same properties as the "true" synthetics, and nearly the same cost as the Group III oil. AMSOIL differs from Group III oils. As a Group IV oil, it uses 100% pure synthetic base stocks. This is why you can run it for longer intervals.

Synthetic oils were originally designed for the purpose of having a very pure base oil with excellent properties. By starting from scratch and building up your oil molecules from little pieces, you can pretty much guarantee that every molecule in the oil is just like every other molecule, and therefore the properties are exactly what you designed in, not compromised by impurities. Synthetics were thus originally a reaction to the relatively poor refining processes available from about 1930 to about 1990. The original synthetics were designed for the Army Air Force in WW II. They simply could not make their high- performance turbo-charged radial engines stay alive on the available motor oils of the time.

One process for making synthetic base oils is to start with a chemical called an olefin, and make new molecules by attaching them to each other in long chains, hence "poly." The primary advantage of Poly-Alpha-Olefin "PAO" base oil is that all the molecules in the base oil are pretty much identical, so it's easy to get the base oil to behave exactly as you like. PAOs are called Group IV base oils.

These PAO base oils have an enormous advantage over mineral base oils in low temperature performance and in resistance to oxidation, which is critical in keeping the oil from forming acids.

Another type of base oil is made from refined and processed esters and is called Group V. Esters start life as fatty acids in plants and animals, which are then chemically combined into esters, diesters, and polyesters. Group V base stocks are the most expensive of all to produce. However, the esters are polar molecules and have very significant solvent properties - an ester base oil all by itself will do a very decent job of keeping your engine clean. So, people who are serious about making a superior oil will usually mix some Group V oils into their base stock.

Oils that are strictly Group V ester oils tend to be better suited for high RPM, hot running, air cooled engines. 100% ester based oils are usually more expensive than Group IV oils, and don't have the longevity of PAO (Group IV) or PAO/Ester mixes oils. Group V oils perform very well in the shorter term. Oils like Royal Purple and Redline are Group V oils. They perform very well in race engines and in applications where drain intervals are factory spec or shorter, whereas Group IV oils are better suited for the long haul of extended intervals.

Whatever oil you choose, know what you are buying. Just because the jug says "synthetic" doesn't mean it is made from 100% pure synthetic base stocks."

Royal Purple not for your Dakota - Off Topic

So according to this guy, Royal Purple is a group V, synthetic oil with ester technology. That makes sense as Royal Purple's Synerlec technology sounds like it is indeed ester based. Here is a description of Synerlec as per Royal Purple: Royal Purple Additive Technology

Also, he states Amsoil is a group IV synthetic with group V esters added to the oil.

Even though he mentions stay away from Royal Purple, I think what he's saying is that Amsoil will do the same for less.

I hate to base my opinion off of one person's remarks, but I had an initial feeling that Royal Purple and its Synerlec technology would be a very excellent choice for the VQ37VHR.

We still need independent tests with OUR motor though...

Old Chuck · 05-17-2009, 08:27 AM

Amsoil is a IV oil and great for everyday use. It exceeds most oils out there and will do well for extended drain intervals. You can learn more then you want about oils at bobistheoilguy. They are the major forum for oil related issues. Most on the forum like Amsoil and it tests very well in engine analysis. German Castrol is also highly regarded. I think a great oil is a must but will not stop the over heating issues associated with the 370Z. Good oil will however, help lubricate as the temps rise to the high levels that are experienced. It is not always prudent to go to a thicker oil as a thicker oil may not penetrate into spaces that are needed as well as a thinner oil. Again, this is not a simple subject and requires much study into the components of an oil and its' uses on a specific engine.

Chan Chee Hoe · 05-17-2009, 10:37 AM

Castrol is U.K.,not German.

import111 · 05-17-2009, 12:45 PM

This confirms my decision to use Royal Purple in my Z. Thanks for the info LiquidZ.

Old Chuck · 05-17-2009, 02:41 PM

I am aware that Castrol is UK however, an oil favored by many is Castrol Gold or German possibily because it is used often in Porsches and BWW's. The composition is stated to be different then the run or the mill Castrol we usually get in the States. You can find all you want to know about this and other oils at bobistheoilguy.com.

wstar · 05-18-2009, 10:15 PM

The stuff about Nissan adding nanoparticles of diamondlike makeup to the oil though... I understand that from a science perspective, but it seems odd to me that that would be the case. You would think if that were the case, they would be making a big deal out of it publicly and calling it Nissan Diamond Oil or something, and the price per quart seems low for industrial grab nm-scale diamond particles to be in there. Was that part conjecture, or is it based on data in the patent, or?

Chupacabra · 05-20-2009, 11:14 AM

I think to much thought is being put into this.
I use Mobil 1, its a true PAO, been used to death, Ferrari uses it on their f1 cars, I think it will be ok on the Z.

I have read that high ester based oils are recommended for people who track their cars in high temperature. Since I don't I am ok with not having nissan ester oil.

Another interesting thing I came up with is:
SAE Technical Paper 2003-01-3119

Which says that engine wear and tear actually decreases with engine oil life. So the more frequent you change your oil the worse it is for your parts. Interesting read.

Hmm could be. i am just saying what I got from the Mobile 1 guys. Called them up and they confirmed that Mobile 1 is in fact a true PAO, not just the 0w40. They said the advantage of 0w40 is its better in gas milage, but if you do not care, they recommend 5w30. I trust them... but you know how it is, they say anything you want to hear.

Anyone have a way to test oils?

Old Chuck · 05-20-2009, 05:50 PM

The best place for oil comparisons is bobistheoilguy.com . They have endless information about all things oil. It is the most comprehensive site for oil related matters. They can get involved about base stocks and actual oil composition but back it up with analysis comparing different oils in different vehicles. If you want to ask questions or just learn, it is an excellent site.
