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.
