Exclamation Everyone with oil temp issues

I encourage everyone with oil temp issues to speak up and call Nissan as I did. It's extremely frustrating to see that in the February Car&Driver their test car has "optional oil cooler $500" & "Optional differential cooler $500" Yet these parts do not exist for the 370z the dealer cannot even order them. If you're car even pushes extreme oil temps in traffic this could be an issue for you and does concern you. At the track I could barely do 5 laps on a 2 mile road course before overheating.

We did not purchase brand new cars with zero endurance, we bought sports cars that are built to handle and outperform the competition at half the cost. The Z is an icon.

I know some of the forum vendors do have oil coolers and I think its great and I might have to order one if this isn't resolved, but I believe we have to fight to get what we paid for. This is what a car forum is all about everyone make some noise and get in their ear about it, or they wont think it's a consumer problem. I will provide the contact info for Nissan North America, those with the base model and moving seat problem I suggest you do the same.

Hi Mu,
I noticed an increase in my oil temp but haven't really figurred it out cause the weather is still a little cold and just started pushing my car because I just done with my break-in. Anyway can you tell us what temp. are we gonna be watching and does it go higgh even if the car is driven on the streets or freeway not being tracked?

Joeyz10 thanks for the question. Once the oil temp starts getting close to 250 under normal driving conditions this is abnormal. On the track mine hit 300. What's even more alarming is the outside temps where only about 55 degree fahrenheit.

What you will notice happening is your rpms start becoming restricted by the ecu in some sort of safe mode. First to 6500 rpms then down to about 3500 rpms.

I also want to add that the car can begin to cool itself if you can keep the revs as low as possible and cruise.

First track experience today ! Some good, some really bad

Here's a link to a thread with what other forum members have experienced.

I can understand the higher oil temps with a turbo car, but why with this N/A V6?? That makes NO sense to me.

On this engine the oil is water cooled. The typical water temp is 200 degrees which means there just isn't enough heat transfer between the two given the only slight difference in temp and limited surface area contact.

With an external cooler you would have a much greater temperature differential, resulting in more heat transfer (depending on cooler surface area of course).

i couldn't agree with you more. to include such equipment in press cars means that they knew they would need them in that context. to make them available to the press and not to the public is misleading at least, outright deceptive at worst.

there is no shame in bringing an oil cooler to help a high-performance engine, a la bmw 335/135. i am guessing that there is some problem for them in bringing the oil cooler to market, such as crash testing or other certification. otherwise, why not?

as an occasional tracker, track durability is a sine qua non for my next car. i hope this gets addressed very soon.

Okay Mu, we will cooperate with you and make this a group complaint to Nissan.

Excellent! I'm going to scan the page from car & driver and post it for everyone to see.

i disagree. When driving normal in stree, you're right - there is not enough temperature difference. However, as you drive the car hard and the oil temp starts to climb towards 300, that should create enough temp difference for the cooling system to do some good......but it doesnt.

So does anyone know what oil temp's the 350z usually ran? Under normal conditions?

I hate to say this but if the car can survive normal day to day street driving with no ill effects then this may be a tough hill to climb with Nissan. However if those in the West have temperature issues in normal driving/parking on the freeways then that is a new ball game.

It appears that tracking will result in the same issues the non oil cooler equipped 335's had. To that end I will either build my own cooler or purchase one from one of our vendors here on the forum.

On a positive note the $500 each price point noted can already be beaten by the forum vendor/sponsor group. So if we can get the job done for less than a grand we may be ahead anyway. Assuming Nissan doesn't void the warranty for helping the car. Sounds strange but I could see it happening.

As they already have made abundantly clear... And you're missing my point; we shouldn't have to buy aftermarket oil coolers, should be stock or at least have the option to purchase nismo. I've spoken to Nissan North America a couple of times already and have been working with the dealership on a resolution. For some of us it's not about the money it's the principal. I bought the car outright and I don't need this aggravation. I didn't buy a sports car with no endurance, no actually I did and now I'm sorry I did.....

Hey Mu, okay i read the car and driver that you posted. Thanks. But does this mean if we will complain to Nissan we have to pay them 500 dollars for the oil cooler? and another 500 for the differential cooler if we want? This should be free because why would Nissan produce a car that a oil temp would go up?
