Everyone with oil temp issues

afsbimmer · 08-25-2009, 04:33 PM

My car just turned 5000 miles; so it is broken in. I see temps in the 220 to 260 range virtually every day. Once the air temp goes over 85 or 90, oil temps increase to these levels, whenever I maintain highway speeds and normal rpm ranges. I guess the real question is: what is considered "high" for oil temp under normal operating conditions, for street driving? For this type of car, I would hope that shifting at 5K RPM would not cause a problem. After all, it is a sports/high performance car. Cruising at 70 to 80 mph and turning 3500 rpm shouldn't result in 250 degree oil temps; at least not for any other car I've driven in the past. Any insight you can provide would be greatly appreciated.

Apparently Nissan considers 280 degrees high as that's where Limp mode is engaged as a protective feature.. Not many (if any) guys reporting that on the street..

Okay, thanks for the heads up modshack. Once its broken in, could you still drive it hard for a little bit and then ease off a bit?

Sure! You can drive the wheels off it if you want. 280 degrees engages a reduced Max RPM limit is all..

No point really. Is your car broken in? (More then 5K miles?). Nissan has already made a statement on this. It is not a problem for street cars. They do recommend a cooler if you track. There is nothing they intend to do.

No, just hit 1k miles on the car today. I'm just really concerned about these temps. I thought for sure this whole thing was hype myself until I saw the numbers myself.

I'm tripping out about these numbers especially since I'm not doing anything crazy in the car. (as my video will show) I mentioned earlier that I intend to AutoX this car and someone said that adding an oil cooler to her will put me into a whole different class. So this issue has got me worried and frustrated. I want to compete in a stock bracket. And it seems like this car's heat issue isn't going to allow me to do that.

ME and many other 370Z owners noticed that this car takes a while to break in. During the first couple thousand miles I have seen the oil temp gauge climb up literally in front of my eyes. But after switching to a good synthetic oil and 7800 miles later, it's a huge task for me to bring the temps up. I'm averaging 95 degrees outside and I'll be surprised if my car crosses 225 F even after prolonged drive. I say wait till your car has 4-5K miles (completely broken in) and switch to a good synthetic like Redline, RP, Amsoil etc. You'll have MUCH harder time bringing the temp up.

Are you attending "brief" autoxing (usually lasts 60-90 seconds with time to cool off in between laps?)? If so you DO NOT need any oil cooler.

Red370 · 08-25-2009, 06:22 PM

Im at about 2500 right now, switched to RP 5w30 and I have a hard time going over 220, and I DO NOT drive like a grandma by any means.

It seems you didn't read the rest of my post. You will not have any issues with overheating during an autox. The runs are short bursts 60 seconds usually and then you have plenty of time before the next run to cool the car.

Can't say it better than that!!

Not sure if this has already been stated but i got this from Nissan Sport Magazine

Quote:

Like most production vehicles, the 370z/g37 was engineered with specific target levels for performance and cooling. Nissan has made it clear the majority of driver will nto experience any engine overheating unless tey engage in sustained high-rev operation. The ECM continually monitors coolant temps and defaults to "limp mode" (cutting engine power and revs) if it detects high temps that could damage the VQ37VHR. That usually results in drivers pulling off the track (or shutting off the dyno) and allowing the underhood temperatures to drop. Nissan Motorsports has developed an oil cooler kit (part number 21300-SS370) and it has been branded a NISMO part, meaning that if it is purchased and installed by your dealer, it will be part of the car's bumper-to-bumper warranty. Is this th eideal solution? No, but iit is an option for those who want to expand the 370z performance envelope.
-David Muramoto

i tryed to type this word for word, its on page 44 of the magazine.

Modshack · 08-26-2009, 04:22 PM

So, Who is David Muramoto?

Nissan's statement does not say this:

"branded a NISMO part, meaning that if it is purchased and installed by your dealer, it will be part of the car's bumper-to-bumper warranty."

They said:

"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. "

Im just copying what he said. Maybe somebody told him something different. I dont know.

I understand. Just that it's dangerous to take the words of a Magazine writer/PR flacky as those of the Company's. Most Manuf. affiliated Publications are subbed out to PR firms.

its not dangerous to copy it, its dangerous to believe it word for word. I dont think its true becuase the solution is to easy and that would mean nissan admits they made a mistake, which i dont think will be happening any time soon.
