Thanks. That's actually great to know. If Nissan doesn't own up to this and correct the problem soon, I will likely be giving Robert a call.

Good Stuff

Just a few updates and trends that I've noticed.

First, I too put a call in to Jennifer and she never returned it. Don't expect too much from her, but do keep calling. Hopefully she'll move the word up her chain of command.

With regards to temperatures, I've noticed that my car does quite well until the ambient temperature is above 75-80. Even in those temps, driving conservatively above 30mph doesn't result in overheating. The problems I've had occur when I have a spirited acceleration through the gears followed by rather abrupt idling or crawling in traffic. (Think jumping on the highway, getting to 80mph with revviing to 5k in each gear, and then immediately getting stuck in bumper to bumper traffic). The car just has zero ability to dissipate heat that it has generated. Once I get the temps climbing after the previously mentioned scenario, there is no turning back from oil temps in the 240+ range until I turn the car off and let it sit. Conversely, I've never had a temp about 250 yet (knock on wood).

I'm about to buy an oil cooler from Stillen but my dealer just implored me to NOT do that. The service manager insisted that he has seen Nissan deny warranty claims based solely on the premise that "the part is connected to the part that failed". Thus, if I had a piston, valve, etc problem, it would be a battle to get the problem covered under warranty with the oil cooler installed. The manager actually said "Nissan has a whole new group of lawyers for the GT-R issues....don't mess with them now." That being said, he did strongly emphasize that Nissan is very good about making changes when there are problems. He believes we'll see a Nismo oil cooler option with full factory warranty, installed by Nissan, and priced very cheaply in the very near future.

I finally asked him what is an acceptable oil temp and what is not. The car's manual implies that temps over 280 are problematic but mentions nothing about an ideal operating range. The service manager, after consulting a number of other guys in the dealership, finally said that "220 is fine, 240 is absolutely not".

Take it for what you will.

"The problems I've had occur when I have a spirited acceleration through the gears followed by rather abrupt idling or crawling in traffic"

Same situation here. I was driving home in 80 plus degree heat, spirited driving but not over 5000 RPM as I just finished break-in. Came upon the usual bumper to bumper rush hour crawl section I experience going home everyday, and I hit 250 and stayed there ................... not good. Nissan says 280, I would be concerned with continual 240 to 260, and it "ain't" even hot here yet. We experience 95 degrees and 95% humidity often in the summer months.

I'd like to recommend that you do not turn the car off and let it sit when you are overheating... please... instead drop to lowest possible RPMs and let the engine oil continue to circulate until it cools down

Yeah, i actually don't turn it off at 250F...that line wasn't entirely accurate. However, it takes a good 20-30 min for the car to cool to below 230F. I've only had the car in the 240+ range once and it had dropped below 240 before I shut her down.

Spearfish, In the near feature doesn't mean anything, Nissan consumer affairs doesn't have the answers. I've been there done that...
If you want an oil cooler, feel that you need it, do it. In the event you have an engine issue, which most likely you will not it is very easy to remove and put back to stock. Stillen's kit is cheap and effective. My car is usually around a comfortable 180 degrees. Except when I'm driving the wheels off of it at the track.

When you are driving the wheels off :icon17: what are your max temps?

Look what came in the mail today!
 

http://i576.photobucket.com/albums/s...r-satisfac.jpgJD Power & Associates asked me to do a FULL 8 pages long thorough review of the 09 Nissan 370z. They have pages asking questions concerning from seats to paddle shifters to driveability to cooling issues etc. On top of that, they are giving me $1 to do the survey! :icon17:

So, what's this oil temp issues you guys are talking about? ;) haha.. I'll let them know about everything that's going on with the 370Z.

I can't wait to do the survey tomorrow. :excited:

I have noticed my oil temps above 240 during normal driving. This is fustrating. This car Needs a cooler!

Glad I decided to check out this thread... I figured it was a "track-only" problem until this thread got so long. Wanted to say thanks to all the guys chasing down this issue. I'm currently shopping and as yet, the 370 is the only car that has made me say "Wow, thats really cool" when I saw it. However since I'd probably be putting 15k / year on it and would want to keep it a long time, the oil temps getting that high during normal driving is somewhat troublesome.

Around 250, no limp mode.

Crap, there was a dollar bill in that envelope? I tossed it out with all my other junk mail lol.

Yeah I did mine a month ago. Now whenever I get one of these surveys, I check to see if there's money in the envelope before I toss the rest of it. I submitted the JD Power one, but I'm not doing any more. One is enough. I got hit with like 5 more after JD Power.

Anyone driving the 370Z in Texas?? I assume the hot weather will push the temperature up.

I sent e-mail to Nissan regarding this issue and told them I'm considering the car, but the high oil temp is A HUGE CONCERN to me. I will see what they say.

There are a few at least, the worst I have seen is 220 in traffic but I am still breaking my car in. This week in Houston it is suppose to break into the lower 90s, so we will see how even tamed driving does.
