220 is about normal for this car, anything above 240ishh while not tracking your car is not ok and need to look into an oil cooler. Not all the 370z have this issue btw, there are many that dont

 

I've read that the decision to go into limp mode at 280 is based on a change Nissan made to their bearings a few years back. They dropped lead as one of the components to ve a bit more "earth friendly" but the new bearing will start to break down under long exposure to 300+ degrees. The 280 degree cutoff is just a margin-of-error temp chosen to be safe. Lots of oils won't break down well into the 400's or higher.

Edit: There is a mention of it here at the bottom of page one..

Two of the guys in the local Z club im in got oil coolers after the first couple thousand miles. One of them had to get an oil change at 1300 miles.
It gets to about 120 F in the day here and about 90-105 F at night.

We drove about fifteen miles (just normal driving) one night and both of the 370 guys said the oil hit 250 on there way there.

People are saying an oil cooler isn't the answer but until nissan does something,it is the answer.

 

Thats not typical at all, I've driven my car through DV where temps exceed that, as well as all over the Palm Springs area and I've never seen my temps exceed 230 and I dont have an oil cooler, going over 250 during normal driving is abnormal and they should have their cars taken to the dealership. Makes me wonder how high they were keeping their RPMs. Didnt the DE engines have oil burning problems? Especially 03's and 04's?

 

Initial 06 Rev-ups had the oil usage issue. This high temp stuff is unrelated to that (I believe that was a ring seating issue). Also note that a lot of 370Z owners report that as the engine breaks in, their running temps have dropped. Let's face it, when you are making this much power with this displacement, you're gonna generate some heat.

 

I can see Nissan moving to direct injection to solve this in the next gen motor.

 

I consistently drive my 350Z in 110+ degree temps. There is NO excuse for Nissan to say the 370 just runs warm. This is a design flaw.

 

Cars like the 2006 mitsubishi eclipse run 270 horse/torque with a 3.8 liter motor, and they don't have heat issues...and they average a dyno even higher horsepower than the 370...go figure

 

Without an oil temp guage in the 350Z, you have no idea how hot your oil is actually getting. The limp mode is a safety feature added to the 370Z. It was added after Nissan discovered that extended exposure to 300 degree oil broke down their newer style bearings over time. Most are missing that the engine isn't "breaking", it's just being protected at an arbitrary temp level by Nissan. I'd call that being responsible.

 

wow, are you insane? I had an 07' GT and was a member of club4g, they dyno around 220whp and 205-210 ft/lbs, good one though, that made my day. I had a Fujita F5 intake, RRE headers and a Magnaflow exhaust, end result? 271whp. 370Z's to include the Nismo, dyno stock between 275-290whp and 245-250 ft./lbs, depending on the dyno. My eclipse also weighed 3500 lbs.

from this:

to this:

 

hey where i say the eclipse runs 270 hp is based off of the rating not the dyno...as for my statement about the dyno, I did some browsing to find that the 06 eclipses seemed to dyno around 250fwhp..Not saying the 370z could or couldn't do more, but IMO the dyno difference between a 370z just warming up and a 370z after heat-soak must be pretty substantial.

 

Very true. So i'm guessing this will eliminate the need to upgrade to an aftermarket oil cooler.

 

I wouldn't get an aftermarket cooler unless I were tracking the car or lived in a climate that got my oil over 250 regularly. I've heard an aftermarket oil cooler can play havoc with your warranty. I would however, be religious in my oil changes!

 

Last engine did the same thing all summer.... new engine doing the same thing.... we'll see if the new engine decides to start guzzling oil too. If it does... no more lemon for me.

 

Mine goes into the 220 area should I be worried?

 

Appreciate the photo. Daily driving November 2009 to today and I have never seen oil temperature at 260 degrees.

 

wow that sucks for you guys

i daily drive my hr in 100+ degree houston weather I never once felt power loss

 

This is pretty unacceptable. Are other sports cars delivering similar performance for the same or less price experiencing oil temperature problems the 370z is?

 

How will turning up the heater as opposed to having nothing turned on at all be better at lowering engine temperature?

 

It takes the heat away from the engine bay and into the passenger compartment.
