Its seems MCR has already reported that the 370z is reaching temps of 135 degrees C on the track (thats 270 degrees F). When that happens the rev limiter is dropped to 5900 rpm (to save your engine at that point).

Why is the Z reaching such a high oil temp in close to stock form? Can we get a factory oil cooler option NISSAN!

What concerns me is that its cold as hell in Japan now too. People will be tracking this car in much hotter temps.

Excuse my ignorance if this question comes off as n00bie.

But does the g37 suffer from the same ailment??????

Tomato: IF I'm not wrong, 135 degrees Celsius is way more than 270 Farenheit. I may be
wrong, though. Maybe our Canadian/European friends in "my350z.com" could enlighten us
on that. At any rate, it's b-a-d news for potential 370Z buyers.

135°C = 275°F

BMW had this problem when the 335 came out. In the first year, the oil cooler was only put on the 'sport' optioned models. They retro fitted the oil coolers to the first year models for people who complained. A couple magazines who tested the 335 had the cars go into ECU 'limp' mode due to temps. Motor Trend being the one that comes to mind:

You would have thought Nissan would have taken note from this debacle?

According to this comparo, the G37 does not have this prob:

Actually, I read that the g37 does have high oil temp too. I never track my car so I won't have a problem with this.

So we're going to trust from one source? And who knows how they drove it and what else they did with the car. And G37 doesn't have this problem.

by the time i finish paying off my current auto loan in 2011, I will buy a third year model 370Z...perfect timing.

I have heard of a few G37's doing this on the track as well. One of the major car mags reported this as well while doing a track test of the G37 coupe...can't remember which one though. I remember them installing a nismo oil cooler to resolve the issue.

...hope this doesn't make it through to actual production although I'm sure its already too late.

Just another example of why you shouldn't buy a first year car.

Even if it's true, I never track my car so I won't need to worry.

Lets hope the info is wrong.

Lets keep in mind that Tsukuba is a shorter circuit, the temps are about 45 degrees F around this time of year.

Installing an aftermarket oil cooler never really works as nicely/trouble-free as an OEM part for mixed use purposes.

Are these production ready cars or early models/test mules?

Interesting that in the Edmund's Inside Line test, the test car was already fitted with a Nismo oil cooler and diff cooler.

http://www.edmunds.com/insideline/do...ticleId=136547

Maybe Nissan knew something before they gave the car to Inside Line to test?

For me this is a big deal, since I would love to have a few track days at Mid-Ohio.

TomatoEvo

Thanks for the info Sirploppy.

Here is the quote from Edmund's:

"If you're someone who does track days, you'll be interested in the optional Sport package with its bigger tires and bigger brakes. You might also be interested in the special Nismo parts fitted to this test car, an engine oil cooler and an oil cooler for the limited-slip rear differential. The engine's extreme output has made it more sensitive to oil temperature, we understand, so if you're looking for the ability to reach redline throughout a long track session on a warm day, the Nismo bits are a good thing to have (especially since there was even serious discussion about making them a part of the Sport option)."

This just became a big deal!

Seems like Nissan knows its a problem. This is what we get for demanding a cheaper price point.

I don't want some bonehead tech at the dealership installing my oil and diff coolers, although I'm sure I will have to concede if I want to keep my warranty. This should be done at the FACTORY!!!

Not necessarily a problem, more like a limitation which should be easily removed by adding oil cooler(s)

From the 370Z owner's manual:

When the engine oil temperature is high, the
engine protection mode, which helps reduce the
chance of engine damage, could activate and
automatically decrease engine power. Driving
while the engine oil temperature is high may
result in engine damage.

yes but you have to keep in mind that the 335 in which on own one is a twin turbo. but i dont see why and NA engine would heat up so fast to such high temps. could it be that the cooling system for the 370z is in a sense "under-powered" for its engine?

not everyone is going to drive the Z or G37 on a track to cause this overheating.... I never saw it and I've had the G37 for a year
