I just got back from the dealership. They said they couldn't find the Nismo oil cooler with the part number I provided -_-

Here's more anecdotal data. Had to go to a place near Phoenix last Friday, about 525 miles each way. From northern Santa Barbara county, that means most of the trip is a boring run through the desert on the I-10. The temperature was over 100 by the time I hit Palm Springs and stayed between 100 and 105 the rest of the way (about 250 miles). There are several long uphill pulls in that stretch (Indio to the Chiriaco Summit and from the Colorado River nearly all the way to Quartzite are 2 examples) so I figured I'd find out whether my Z has issues. In the heat, I mostly ran between 75 and 85 MPH (except for a few short bursts at higher speed while dusting off folks who thought they wanted to play but who found out they weren't in the same league with a 370Z). BTW, the A/C was on the whole time.

Bottom line is that the oil temperature never got above 238 and then only on long pulls. On average I'd guesstimate that the oil temperature ran around 225. Like I said, this is just my experience with my car and my driving. I make no claims about broader implications. What I will say is that I personally am no longer concerned about oil temperature problems. YMMV.

FWIW: I ran this same route again today. The main differences between the previous trip and this one are that the ambient temperature range today between Palm Springs and Phoenix was 100 to 110 and I'm running Mobil 1 now vs Castrol GTX last time. As before the average guesstimated oil temperature was 225. The highest oil temperature was 240, observed during a long uphill pull heading East from the Colorado River crossing.

i really dont feel like looking through 47 pages but has anyone used royal purple and what were your results?

I just got my 370 2 weeks ago.. I have put around 1200 miles on it(drove it a lot to break it in) and the other day sitting in stop and go traffic in the great state of texas my oil temps reached 260, I pulled off the highway on the access road and before noticing how hot my oil was, i decided to do some "spirited" driving. Temps just kept rising slowly until I let it cool in a parking lot it was really close to 280. I will be bringing it to my dealership on mon. or tues. but when I called i was assured that this was normal? and that the car was meant to run this hot....I DONT THINK SO. Long story short im pissed i just spend 30k+ on a car i cant drive above 4k rpms in the summer. Not okay by me.

It hit 102 yesterday afternoon in Dallas and I was in stop-n-go traffic for about 30 min. My oil temps never exceeded 225. I have the 7AT and the AC was full blast the whole time. Of course no spirited driving, too much traffic. It seems there's a lot of variance from car to car. I'm wondering about the accuracy of the oil temp sensor. FWIW, the outside temp gauge swung between 104 -108 during the drive. I expect that it picks up additional heat off the road surface and engine since its mounted somewhere near the radiator.

Tim,

I'm planning on using Royal Purple when I swap out the factory fill. If you hear anything interesting make sure to post something...

thx,

Well FWIW regarding the oil temp sensor accuracy, my oil temp used to rest at 220-225*F when driving and spike up to 250 pretty quickly during aggressive city driving (mostly due to higher RPMs).

After adding an oil cooler kit with a thermostatically controlled plate set at 180*F, my oil temps seem to rest at about 185*F when cruising around town and about 195 on the freeway. They go up to about 220 during aggressive driving, but that's as high as I've seen them go so far.

The important clue here is the oil cooler sandwich plate is set at roughly 180*F, and I see my oil temps rest around 185*F. Without having an intimate knowledge of how the oil plumbing works inside the oil pan, to me, that says the temp sensor is likely accurate.

What kit do you have Rackley

Thank you. Rep+1 :tup:

Our forum member DannyGT also has the GTM oil cooler. Feel free to search his s/n as well.

just to make sure i am clear. there is no problem with this car an oil temps for street driving correct? these problems only surface on hard track driving?

i just want to make sure im not going to have problems if i step on the gas on the highway etc..

thanks

You'll be fine.

People who are complaining most about oil temps are the ones that are driving their cars hard enough to cause issues with oil temps for just about any car without an oil cooler to have "issues"...

Really depends on your definition of "step on the gas on the highway". If you mean you want to pass another commuter in your nice-looking car, you won't have any problems. If it means you want to double the speed limit for a long time, maybe :) Even then, highway isn't so much the issue, it's aggressive low-speed driving with lots of repeated accel/decel cycles that really runs the oil temps up. And even then, you won't limp-mode the car on the street, I don't think anyone has reported that yet. You'll just potentially wear out your oil and your engine faster.

yea, sounds like i wont have a problem. i like to step on the gas here or there, pass some cars and go around the bends.
