Say hi to the fellas when you get to work at Nissan tomorrow.

One of the nice things about being an American (a country I spent 22 years defending) is I get the right to complain.

Get over it.

The 370Z has an engine protection system that reduces peak engine speeds when the oil temperature exceeds recommended levels in order to protect against possible engine damage. Aggressive driving of the 370Z on a race track at sustained high engine speeds can cause increases in oil temperature and may activate this engine protection system. To avoid activation of this engine protection system and these reduced peak engine speeds, Nissan recommends an oil cooler be fitted to the 370Z before driving it on a race track. A Nissan Motorsports accessory oil cooler kit is available for customer purchase through authorized Nissan dealerships for race track use. The part number is 21300-SS370.

An oil cooler is not necessary for normal operation of the vehicle on public roads. The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers. Value has been a core principle of the Z car since the original 240Z and we choose to uphold this core principle by not adding additional costs that are unnecessary for normal use. For those individuals who choose to drive their vehicle on a race track, the oil cooler is available as an aftersales item.

The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty. However any damage caused by the installation or use of this part is expressly excluded under the terms of the Nissan New Vehicle Limited warranty."

Very interesting data. This remains one of the main reasons why I have not upgraded to a 370Z. Living in South Florida, I do not feel like concentrating on oil temps instead of just enjoying the car. Personally, I am hoping that Nissan will at least offer the oil cooler as an option for the 2011 model year. Some extra HP would also be nice.
Otherwise the 350Z will be traded in for a 2011 Mustang GT.
I love the stying of the 370Z, and the performance is excellent for the price, but I've been there and done that with Nissan with a Rev Up oil consuming 350Z. Nissan should learn something from the Toyota fiasco and be proactive in dealing with customer complaints regarding their automobiles. I would argue that limp mode could be a safety issue if it were to engage at an during spirited driving.

Enjoy your GT...

why some people take criticism of a car as a personal attack is an interesting phenomenon probably limited to those with about as much common sense as a monkey, meaning none

Constructive criticism is welcome here. But you just don't read well. Nissan does offer an oil cooler as an aftersales item. You mentioned an oil burning 350Z and inferred the problem has been carried over to the 370Z. High oil temps are only an issue on the track. So, go buy your GT and eat a banana.

if you review the collected data it is clear that oil temp issues were present on both the street and track.
all I am saying is that for me personally, in South Florida where it is very hot at least six months of the year, I will not buy a 370Z unless I can get an oil cooler installed at purchase that does not affect the warranty.
The 2011 Mustang GT by the way will have over 400 HP.

If it was an option then cool. But that's not what Nissan was talking about, or the poster I quoted. Nissan's statement was explaining why they didn't make it standard equipment on a street car. Where does Nissan say that the 370Z is a trackable car straight from the factory? And trust me, based on what they're charging for just the parts it would have equated to a $700 or so upcharge on the price (especially since you have to also figure in installation labor at the factory), not $350-$400.

Again, IMHO it's not a weak argument and they did the right thing.

BTW - If your car is going into limp mode under normal driving conditions then you've got a legitimate warranty issue that Nissan has to correct. If that means they install an oil cooler for free, then that's what they should do. But how many people are having oil temp problems under normal driving conditions? Hardly any (maybe none), I bet...

You don't currently have an issue
You think you might because of what you've read on the internet
You want them to resolve this (nonexistent problem)
You threaten them if they don't

Unbelievable.

Go buy your Mitsubishi or Mazda. I'm sure their customer relations department will respond in a similar fashion to the issues you think you might have with those cars..

:shakes head:

I'm not trying to say that they have shoddy workmanship or poor quality. But it's just a fact that not every engine is exactly the same. It's not like EVERY engine has the same HP numbers to the wheels, or that the valves on each car seat exactly the same. There are so many variables that come into play that make each engine different.

But my point is that you can always Google the question if really want to know. And maybe a search at bobistheoilguy would yield some good answers as well.

Many are claiming dangerously high (or at least problematic) oil temperatures under certain conditions. My question isn't what an ideal oil temperature is, because I feel under normal conditions (both driving and environmental conditions), most will find their Z operating well within the limits of "normal oil temperatures".

My question is what do you expect our oil temperatures to be at, with the understanding there is no factory oil cooler, assuming you're tracking or sporty driving on a hot day?

If the expectations of the 370z owners are that the car should be running at a perfect 190-200 degrees on a hot, track day without an oil cooler, I think the problem may be our expectations, not the engine.

So then I guess I would need to find out at what temp the type of oil I use starts to break down and lubricate as well.

But what complicates things is that article explaining that the problem for this car isn't that the oil gets so hot that it starts to break down; the problem (according to the author) is that in an effort to be more 'green', Nissan changed the type of metal they use in their bearings, and the new metal is less durable under high heat. The claim is that even if your oil is okay at, say, 280 degrees, the bearings aren't -- they'll start to degrade. You guys know which article I'm referring to? The one by Mike Kojima?
