Everyone with oil temp issues

NIZMOZ

That's interesting. I race my 350z HR model and have no overheating issues with the oil or coolant. I have ran in 105+ degree heat, and the temp has only moved half way on the gauge. I used Amsoil and it has done well. Running up to hours at a time. No one has ever mentioned anything about overheating issues with the 350z. The only ones that do are the boosted ones.

The 350Z didn't have an oil temperature gauge, the problem went undetected by many.

You don't need a oil gauge to tell how the temps are. If the temps were a issue the oil would be coming out pretty dark.

That would depend on the oil and how well it is handling the heat, a full synthetic is always going to do better.

These engines have always had hot oil, but the new design has taken it to a new level.

On the way home tonight, some spirited driving after warm up, never exceeding 5500 RPM. In this order: spirited driving, crawl in rush hour 10 minutes, more spirited driving, another 5 minutes of stop and go, regular driving another 10 minutes to my home. I hit 250, and the outside temp was 80, sun down in the sky! I would say this doesn't have much to do with break-in. If I can hit 250 at 80 degrees with this kind of driving, wait until the outside temps hit 100.

^^ I didn't say that.

Well, I had my first go at a track today. This oil cooler issue may be moot when street driving in most cases, but it's a real issue with anything on the track. I had to keep backing off as the temp hit 260 to protect the engine as the car is my daily driver.

I did some hotlaps in another 370 driven by a professional, and he essentially said that Nissan $hit the bed by leaving out the oil cooler. One definitely belongs in the car.

On the flip side, the 370Z is a dream on the track. I had a blast with mine, and the laps with the pro were eye openers with showing just what this car can do. My buddy almost puked after two laps with him!

I had my car on the track this weekend as well. I have the Stillen oil cooler kit and it seemed to do the job well. Ambient temperatures were around 98F at Barber Motorsports Park in Birmingham, AL. The temp indicator in the car got as high as 103F but I'm not sure if that was right. On the track, the oil quickly heated up to 260F but never surpassed this point. I pushed the car hard for 4 twently minute sessions on Saturday and Sunday and never had any problems. The oil still looks brand new (Mobil 1 5W30 synthetic) and I never had any limp mode issues. From talking with other drivers of other cars, temps around 260-270 are typical. The oil cooler works, too bad it didn't come on the car...

OK, car noob here. I am trying to understand what is considered good and what is considered bad. I read most of this thread and I see people posting various temps under various conditions. I must say that I can replicate much of what is reported, i.e. 220 with normal street driving, etc.

But every once in a while, I see what appears to be posts that go unchallenged that say 250 or greater = BAD.

What is the objective basis for this "> 250 = BAD" statement? Is there a document from Nissan or some other recognized credible source that indicates that > 250 in the 370Z is bad or is this general automotive common sense (which I have none of I admit - this is why I am asking).

Thanks all - looking forward to insightful responses.

Chris, that's awesome you got it to the track... I know what you mean about the difference between us mere mortals driving, then getting in the passenger seat and letting a pro drive... I had that same experience when I brought my wife's ISF to the Bondurant School... if my wife only knew what we did to the car that day ! In any event, please post a track day thread if you have time ! thanks

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.

Spoke with consumer affairs today with no result basically they said the issue is with the engineers, asked about warranty if dealer installed nissan motorsport cooler would the warranty be intact, I really did not get a solid answer and no they will not put that in writing it would be a case by case basis. So sounds like we are in a wait and see mode to see what comes out in the future or go with an aftermarket solution and take our chances. Outside temps around 94 oil temps 240 to 260 range.

Same here, in plus 90 degree heat, I can hit 260..... and that's without redline, I usually never exceed 5500 RPM. I noticed the previous poster in his dessert run never passed 240. I think steady highway driving at 80 to 85, even in a pulling uphill situation, doesn't send the temps rocketing like up and down shifting through the gears, in-town driving........ at least that is my experience. Steady state freeway driving seems to force enough air through, even in 90+ temps, that I don't exceed 230......... get off the freeway and spirited drining in-town ................... hello 260.

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.

260 = very bad
