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, 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.
