I think as long as your not flogging on the engine within those 10 miles, it should be fine.

I would venture to guess it's not gonna be anywhere close to a 25 row cooler. Nissan won't do any retroactive modifications for those of us who have our Z's already, but I do hope we don't get burned for warranty work because we have one installed. If I were to install that very same Nissan branded oil cooler for example, I hope Nissan and the dealership sees it as an approved add-on/accessory that doesn't affect the drivetrain warranty. Yes, they should have thought of it before, and they should do a retroactive for us simply because it's not an upgrade or option that should have been left out, especially for a sports car with a known issue....and they did know this! Otherwise, why have built in countermeasure in the limp mode protocol and install one in the upcoming model. They should help us out....doesn't mean they will, but they def should. Having exprerience limp mode, it does pose a possible danger while driving. Imagine suddenly not being able to rev past 3k rpm's while in stop and go traffic... then the traffic clears and everyone around you is doing 60mph. This happened to me before I knew of the limp mode issue and I can honestly say it was a nerve racking experience. Obviously not as dangerous as a stuck throttle or not having brakes, but there is an element of danger and the possiblity of a crash.

I say we post our concerns on the Nissan Facebook page and let Nissan know we as a community want this done retroactively. We're a big enough community to have some say in this don't you think.

I do not expect an oil cooler leak or explosion, but if one were to occur I would like to think Nissan would honor their warranty since I had it all done at the dealership.

I know I am a dreamer but if I were on the jury it would be this way.

If you built the velcro oil cooler I would not expect the same verdict.

I have a few questions. Not picking bones with anyone, just want to understand this a little better.

1. Didn't Nissan implement the "limp mode" because they switched to a new "green" bearing material in our engines? I thought I read it someplace and it's possible the limp mode was created as a result of that (material specifications), nothing more.

2. Manufacturing tolerances (especially these days) should be tight enough where variances should not cause engines to operate vastly different from one another. While break-in procedures can vary widely, could that really cause an alteration of the engine's ability to run at normal temperatures?

3. In the case of the owner who has owned both an '09 and '11 model. I'm curious if the '11 model is running higher oil temps because the engine is still fairly new. Has anyone experienced reduced oil temperatures after ~25k miles of usage?

Yesterday I drove from San Jose to San Francisco (about 50 miles) on the freeway in moderate temps and light traffic. My speed was set at 68mph (lots of LEOs around so used cruise control) and I was running pretty steady at 210 degrees the entire time. To me that seems fairly reasonable, however if I get on the car hard it doesn't take long to get up to 240-250 degrees. I've never pushed it over 260 degrees before.

Concerning the warranty issue. If you install your own oil cooler and you do a bad install leading to something like an oil leak or ripped line then you are probably on your own for the warranty unless installed by Nissan. However, short of that you should be fine. I can't think of any way Nissan can come back and say that you're install of an oil cooler led to the failure unless you failed to put in the proper amount of oil or did something along the lines of the scenarios I just mentioned. Us 2009's are going to be losing the warranty soon :(

We are on the same page. I bought mine in 2010 and then got extended warranty on first year model, so my intrest here continues until 2018.

Thus far I've had almost no warranty issues other than an airbag sensor going bad leading to a flashing red light.

I've read that Nissan decided to drop lead out a a tri-metal formula a few years back to go "green". As a result, the bearing started showing breakdown at sustained temps over 300 degrees and this is the reason for the 280 degree limp mode. I'll try to find the article.

Edit: problem is mentioned in this article: http://www.modified.com/tech/sccp_08...e/viewall.html

Mine is the same as DarkZide, I have been out there on 2 different days in the last month and never saw it get over 250. What gears were you using? I found that i spend the majority of the time in 2nd or 3rd unless i get behind someone going slow, then I'll change up to 4th or 5th. That being said, I don't think that Nissan will change their stance on adding an oil cooler to an existing Z but it would be nice. Depending on how it runs next summer in the desert I might be interested in a small one and it would be nice to have it covered under wrranty even if i pay to buy it and have it installed.

i just went to dealership to get my 09 z refinance and maybe trade it in for 2012 model,,i asked him if oil cooler come in as standard feature and he said no addition feature for 2012 model?? so i dont know what to believe,,even nissan website didnt mention abt oil cooler,,

Does the Nissan website mention the power steering cooler? ;)

Nissan and Infiniti - Nissan Announces U.S. Pricing for 2012 370Z Coupe, 370Z Roadster and NISMO 370Z

It's official from Nissan. Good news for me, we'll see if nissan does the right thing for previous model 370z owners too.

Dealership salesman arent always knowledgeable on all aspects of the cars they sell, especially until that car hits the showroom floor, even then they may not know all the facts, go by the official Nissan announcement it is legit. ^^

i guess i was looking at wrong stuff,,but anyway my dealership is getting one car coming in two weeks i dont know if i should trade it in or not!!

It depends on why you want to trade it in, do you need the oil cooler?

You forgot to mention cabin noise.
I can't believe you actually bought such a piece of crap. :rofl2:



I've said it before, and I'll say it again... Between the magazine articles and the presence of an oil temperature gauge, there's more paranoia about oil temperature than actual occurrences of limp mode.
There seems to be a lot of variation in the temperatures experienced by owners which makes me think that the accuracy of the OEM oil temperature gauge is suspect.
If the car didn't have an oil temperature gauge from the factory, we wouldn't be talking about this as much. As far as the track guys are concerned, they would just install one along with their oil cooler.



Just wait until the Miata doors are offered as standard equipment on the 2015 model!
I could just be talking out my butt here, but I'm pretty sure that some risk of major mechanical failure or a safety hazard has to threaten a large number of cars in order for there to be a recall. It took several fatal accidents and a huge public outcry to trigger a recall on Firestone tyre equipped Ford Explorers. Nobody is dying from limp mode and a few guys flogging their cars to the point that the computer implements a safety measure to protect the engine isn't going to trigger a recall. At the end of the Firestone/Ford Explorer tragedies, it was determined that user error (improper inflation) was partially responsible for the tyre failures that caused deaths. I'm pretty sure that pushing the car to limp mode would be considered the result of improper use of the car by the manufacturer and NHSTA despite what we as enthusiasts think is the "proper" way to use a 370Z. :driving:
As enthusiasts, the members of this forum represent a small number of the owners of the 370Zs sold, and amongst the membership, there's an even smaller number of people with oil temperature issues. I don't think it's a big enough issue amongst owners to warrant a recall.

On the other hand, I could see how throwing an oil cooler on the current year's car so that the magazine writers start publishing glowing reviews about the 370Z would be a worthwhile investment in salvaging low sales figures or even boosting interest in the car.
