I am looking for another 2009 370Z with automatic transmission that is willing to datalog theire Z. What's your Z specs and where does it reside?

What you could determine from this sort of testing of several cars is what causes the temp problem (as in, how much revs for how much time in what ambient conditions cause what oil temp peak). It might be nice to have more specific numbers on that, and to know whether it's a car-to-car mfg variation versus a difference in driving style and conditions that causes the varied experiences people are seeing on the street.

You'd need to log everything related though (all engine parameters, the RPMs, load, various temps, etc graphed over time), we'd need to do it with several different weights, types, and brands of engine oil, and we'd still need to use a standardized regimen of testing, such as warming up to a certain water+oil temp, then driving X miles in Y gear at Z RPM, then switch to another set, etc.... which is really hard to do on the street with traffic and stoplights to contend with and so-on. We still wouldn't be able to control the ambient condition differences, but at least if we can keep it down to that as the only significant variance we could learn a lot.

But honestly, to me that sounds like a lot of work for not much benefit. It still doesn't tell us jack, ultimately, about how oil temps are affecting engine life in the long term. Only destructive testing in a lab can do that.

Yeah...that the a good way (destructive testing in lab conditions) that I was thinking as well; however, I do not think anyone would sacifice their 3.7Z engine for a destructive failure test. Alternatively, the datalog method of 370 engines may enlighten other 370z/37G owners to the preceive oil temp issue.

Yes, one would have to datalog all the engine parameters including outside temps and conditions and driving conditions. I believe Nissan uses the newer version OBD III consult in the 370Z that I currently do not have. Maybe Nissan would be willing to provide one for testing purposes-hint!

Any datalogger that supports the CANSF protocol should work. There are several on the market that do the job. I can't really help personally, as I've already modded my car significantly from the baseline in terms of intake temps, oil cooling, and intake/exhaust boltons, with more to come in the near future.

i'am a new member looking to buy a new 370z ,i live in hot as hell lake havasu az .116 yesterday . i test drove a new 370z auto w sport pkg and was able to get oil temp to 245 in less than 10 miles of driving,first 7-8 miles on hwy temps were around 220-225 then i on purpose down shifted to keep revs 3-5k for a mile or so temps rose fast to 245 then i backed off being a new car i didnt want to run it at 6-7k rpm as that would have really raised the temps. i think regular driving in our extremely hot conditions will require a oil cooler,my sales rep is checking with a nissan rep about heat issues here.lake havasu regulary gets past 120 in summer months!!

I'm living in Phoenix and took the car out the other day to see how high I could get the temps. My temp gauge read 114 (I believe it). I kept the RPM high and then did about 4 2nd to 3rd pulls all the way to red line and the highest the temps got were 245. After that, the temps quickly returned to about 230. I have no problems during normal driving. 09 6MT Sport.
