Everyone with oil temp issues

If you don't do track days or other sorts of motorsports and run good synthetic oil and change it frequently, then you should not have problems. No need to get excessivly paranoid.

Most track driven cars should have an engine oil cooler. If you participate in motorsports then get the cooler for sure. If you don't, then don't worry so much.

260 degrees is where the properties of the bearings in the engine start to degrade, remember these are soft metals with low melting and softening points. Now there is quite a bit of reserve built into engines so 260 degrees under street driving condtions won't harm the engine. On the track there is a posibility. 280 degrees as the maximum safe temperature on the street is quite reasonable.

If your 370Z has an aftermarket turbo, you are hot lapping and your oil hits 260, time to stop. Same if you are loaded up with performance parts with your rev limit set higher. If your are hot lapping in a stock car and your temp hits 260, time to slow down and cool the oil. If you are in traffic on a hot day, the load on your engine is light and you can drive ok.

The VQ37VHR is not the only Nissan engine to run high oil temps. The RB26 and the SR20 do as well and those engines have pretty good reps.
