Really? how easy was the install?

you guys are on crack...i don't care what nissan says...running @ 235f while cruising on the interstate in 6th gear at 80mph on a flat smooth road isn't right. granted it was hot as hell ambient (like 95) but that just doesn't feel right. i think 190-200f in everyday driving is appropriate.

i'm getting a 34 row oil cooler with thermostatic plate to prevent long warmups during the winter and running redline 5w30. will be fine on track days and in the future if i get forced induction.

good luck driving without an oil cooler in the southern u.s.! clearly an issue that nissan should fix.

wish i would have said that

as far as this oil issue goes in my case this is what i have seen with my 09
with 5000 miles on it. in july and and so far in august with outside temps averaging 95 degree's my oil temp is hanging around 210 to 240.
this is stop and go and interstate travel.i am not a gear head so i don't
know what normal should would be. i use 5w30 mobil one and the only thing i have noticed
is the oil seems to have a darker color in between changes than it had with my
350. i love the car but i use to never have to worry about checking the oil at every fill up. at least it doesn't burn any oil.

Apparently, you're the hypocrite. All the data suggests that oil temperature is an issue with the 370z. I've haven't been to another forum (S2ki, Stangnet, evolutionm, ClubRSX, etc.) that had as widespread concern about engine oil temps other than the 370z forums. Heck, the my350z forums doesn't seem to have these issues either.

The cooler was the single best thing I did for my car. Even with a few little headaches, I'd do it all over again.

Hello,

My 370Z has about 350 miles, I drove it sporty to hard in a Malibu canyon by 80 degrees temperature and the oil gage showed 270 degrees for a few miles then went down to about 250 degrees for the rest of the way until home (10 miles). From what I read the car runs hot and I am worried that if I install the Stillen exhaust and air intake and something wrong happens due to the heat they will void my engine warranty. Should I be worried? What needs to be done?

I'm surprise your car did not went into limp mode. I would not worry other than getting mad, that is why you have the factory warranty.

However, the Stillen exhaust and air intake does not have anything to do with the car oil overheating. The The Magnuson-Moss Warranty Act protects you from stupid service department that might want to blame other problems on exhaust and air intake as per your case.

270... dang that's hot. even in 85F in my area my oil temp is no more than 220, moderate driving to sometimes wot. :D

i know how involving malibu canyon is, so i dont doubt it. :p watch your brakes boil
coming down tuna canyon quickly. lol

Give the car time to break in....Most have found oil temps will drop and it becomes a non issue after awhile..

Thanks guy, I will change the oil after 2500 miles and get some better oil than Nissan provides the car with. I am not too worried about the oil heat issue as long as I do not see 295 degrees I feel ok.

Concerning Malibu canyons, they are tough on the car but not that tough... Not even close to what the car would experience on a track which is what had me worried. I guess a dealer installed Nismo oil cooler might help, better oil and a Stillen front bumper which give more air to all the cooling parts.

This high oil temp is bugging me.

92° outside and while just rolling down the highway (with no one in front of me) at 68mph I was reading 245° which sounds a bit hot for not even being over 2700 RPM. It did not go down for MILES just stayed at 245°.

I switched over to redline 5W30 this weekend when the car hit 2339 miles on the clock. I was hoping that the oil might make a difference, but that is not the case, in fact I think it is running hotter.

Nissan owes me an oil cooler...

its getting hot in Texas. my z has right at 10,000 miles and worst I've seen was driving back from San Antonio to Austin couple weeks back. outside temp was 102F... Oil temp 230-235. Cruising sixth gear around 70-80 mph light traffic on I35. While not terrible I do think thats hot for cruising in top gear on a flat smooth interstate freeway. Once I exited the interstate near home and sat at the first red light the temp came down to 220 pretty quick.

Nissan's answer to you is that 240-250 is not a problem (as far as they are concerned). I do mostly agree with that because if you didn't have an oil temp gauge you wouldn't be complaining. I.e. sans looking at the temp gauge and freaking out the car wasn't misbehaving.

I've probably hit 260 on the street when pushing it a bit without a cooler, again not really a problem in small doses. If you're going to push the car hard then you need a cooler, otherwise put some black tape over the gauge and forget it's there until you hit limp mode for the first time. If you manage to achieve limp mode then you need a cooler.

Nissan knew about the oil temp issue.
That is the main reason they put a oil temp gauge in the car.
But i do agree with one poster if it wasn't there no one
would be so worked up over it. i'd rather have a better coolant
temp gauge than the cheap one we have now to me that is
more important.

until the oil catches fire, its all good.

Yup. The flashpoint of clean oil is over 400F so I think you're safe. Contaminated (old) oil drops to around 300F.

Austex - that is normal as far as I can tell. Until i put a cooler on the car that is exactly what I was running - to and from SA from Austin on IH35 or 281. I have a project in SA and make the trip often. You have no worries mate. :tiphat:

Do the 2011 370z's have oil coolers?? I just ordered one with the sport package and plan on running it hard.

Im sorry keno but I have to ask. Did u order your car online that you couldn't check or ask that? I don't think it comes with oil cooler. Nissan made it clear that is an option item.

No they do not come with an Oil Cooler, and the way I understand it, if you get one installed you void your warranty.

If you install the Nissan Oil Cooler will not Void your Warranty.

Also NO Dealer should void the warranty of your car for any aftermarket parts installed on your car unless the aftermarket part is the cause of the problem. They only can void the warranty of the part damage and not the whole car.

Read about the Magnuson Law.

oh boy... this is wrong, move along folks

:tup:

I am verrrry sorry........I have read on the forum many times that it did void the warranty. I even read a thread yesterday that was a survey that was taken here a few months ago that had that in it......


Honestly.....I HUMBLY APOLOGIZE....I was wrong and thank you travisjb for pointing that out

Oh don't worry there's nothing wrong. On the other hand you are one of thousands that dealer take atvantage of their ignorance and try immediately to void warranties of the car for them to make profit. Now you know theirs a law that protect the after market parts for any car. So if I sound rude my bad. Wasn't my intention. :-)

Yeah, didn't mean to pile on and no need for an apology - issue comes up a lot on this board and we don't want our fellow Z owners to be taken advantage of... suggest you take the time to read this: Magnuson?Moss Warranty Act - Wikipedia, the free encyclopedia

But which side of the argument is the Burden of Proof on?

Just a point of interest, you MAY want to post this same survey up on the G37 forums, they have been reporting the SAME issues as 370Z owners regarding oil temps...
That would only strengthen the argument for NNA to do something about this.

From what I can see not a SINGLE person has had an engine fail due to these supposed "high" oil temperatures. The only reason this whole thread exists is just straight up ignorance. How many of you guys on here bitching about the "high temps" have EVER had an oil temp gauge in another car? How do you know that 240* is too high? What does your wife's minivan run at? NEWS FLASH!!! It's probably the freakin same!!!

Nissan didn't put the gauge in the car because they "knew it was a problem" That's the dumbest thing i've ever heard.. almost. If they knew that was a problem, the LAST thing they'd do is put a gauge that shows every person with internet access that there's a problem. What Nissan did do was give themselves a giant headache by putting that temp gauge in there so you guys could bitch about high engine temps. If the coolant temp isn't getting too higih, then it's probably not overtemp. I bet if there were a tranny or diff temp gauge in there, you'd bitch about those temps being too high as well. Maybe some EGT gauges scattered about would be better?

does a survey = bitching?

your note is not very constructive... this thread is about collecting data... the data covers driving conditions and temperatures... there have been some that have experienced 'limp home mode' as a result of high temperatures... that is a very different situation than running at 240f or even 270f... limp mode kicks in beyond those temps

I understand the point of the survey, but if you look through the last several pages, it's filled mostly with bitching, not information sharing.

Sorry if I contributed to further trashing this thread. All apologies.

no worries... yes, some people get worried... yes, people should keep it in perspective... and yes, there are some legit issues here - like folks that get 300f not on a racetrack

This is the way it work. And I will use the oil cooler as example but it can be any aftermarket part.

1. You go and purchase any oil cooler (professionally manufactured and tested) and install it on your car.
a. You take your car for oil change and the manager tell you, that your whole car is out of warranty because of the oil cooler. That is a BIG NO. They can't do that.

b. You get a Check Engine. They tell you they can't check the car until you remove the oil cooler cause that will void your warranty. BIG NO. THey Can't do that.

c. Your Radio, or GPS, or your AC goes bad. They use the oil cooler as excuse to charge you more when that is covered under warranty. BIG NO.

2. The dealer need to follow the recommended steps before making any desicion. So to answer your question who has the burden of proof.

You purchase the Oil Cooler from Nissan or from Stillen. Both are proof to improve one way or another the oil temperature (not fix it). They are both professionaly manufactured and tested. You take your car to the dealer because you have a check engine light. The dealer has to take your car like any other regular nissan for check. They connect the computer and they need to perform all the check necesary to identify why the CEL is on. Let's Say the CEL is becuase you are mixfiring or another type of failure. And the dealer come back to you and tell you. The problem is the oil Cooler you installed. Is not covered under warranty so is $1,200. At that point you have the right to request the analisys they did and how they reach to that conclusion. With the paperwork, you call the manufacturer of the oil cooler, and you explain that their item cause a problem. They definetively will say No Way. Then you ask the manufacturer that they need to put in writing why they are claiming their product is not their problem.

Sadly this is a back and forward calls and paperwork, you also have to search online, ask here for opinion. After you have all the necesary documentation that either is or no the oil cooler then you go agains the one that is wrong and have it fix. Is a tedious process, I've been trough that with my Eclipse 4G. But at the end you will find out that the dealer don't have a clue what the Magnuson Law is and 90% of the time they are wrong and they just want any excuse to void your warranty and charge you full price.

Thank you very much for that information..... +1

Sorry Anthony but this Oil Temp topic has been addressed to Nissan and they already replied with their answer, they won't do anything. I know someone posted their letter here in the forum but in a summary Nissan said that, they decided not to include the Oil Cooler to have the car with a competitive price. The installation of the cooler would have put the price of the way out of hand of normal people that want to drive their car as regular cars and not racing. That is why they decided to have the ECU protection system "limb mode" on the car to protect the engine. But for those enthusiast that are planning to use the car for racing, Nissan has their own Oil Cooler and they give their part number.

Here is the letter: Nissan 370Z Engine Oil Overheating - Nissanhelp.com Forums

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.

Your welcome :tup:

Not to mention this thread is OVER a yr old and the topic has been covered so many times!

I agree, it's time to close this thread out... I'm going to post the final results of the survey... I took some time on a flight tonight to roll-up the data in a spreadsheet... here it is... open to discussion for a few days, then we'll shut down this thread if there are no strong objections
