Oil Overheat IMPORTANT UPDATE

mannyz · 05-18-2009, 12:22 PM

I do have japanese frnds as well, but they r not in the car enthusiast, so I cannot make them call Nissan on my behalf it will b a hassle for them. But it will be good, who knows maybe Nissan Japan, know and fixed the problem and the US are just doing it on purpose removing parts to sale it separate and make more money. IDK these days you cant trust big companies. =(

I am still not certain, however, how improper that temperature is for a car (not having monitored oil temp regularly in the past on my 350z). I wasn't flooring it nor was I excessively speeding to generate that temp, but it only happened 3 times and it dropped back down within 2-3 minutes. On the two times up to Tahoe, it occurred while going up a hill and on the way back it was on a very gradual gradient.

But what exactly does that mean for the car? I'm assuming, based on the previous posts, that these three brief bursts into 260 will not damage the car and it did not seem to affect performance. What exactly is "normal" and when do temperature spikes become a "problem" for a car? How frequently do would they have to happen and how long "should" they take to dissipate? I understand about what triggers the "limp wrist" mode, but I haven't gotten anywhere close to that. Temperatures were pushing 94 degrees on the drive and it took 8 hours. So I'm more concerned about the 240-270 range and what means to a car over its lifetime.

I intend to track this car from time to time, so I will be forced to add an oil cooler regardless. The overwhelming feedback has been that a full 20-25 minute run on the track - much less an entire day - is pretty much impossible without one. But I am also interested in what is, or should be, considered "normal" conditions off the track. Emotional opinions about Nissan knowingly releasing a sports car that overheats on the the track aside, does anyone have any engineering perspective on this?

OK I Called Nissan, I have to take the car to the dealer, thats the first step which I knew. But I reported the problem. My Reference# is 6496979. I will be collecting and printing information from this site, Edmund and everything you guys collected already, because I know that when I get to the dealer I have to prove it and it will be hard. You know how cars behave infront of mechanics. I'l keep you post it.

I have posted an interesting update in the sticky section on the oil temperature "issue." It's kind of a biggie after talking to Nissan. They made some very good points.
