For example, how about on the G37? Same engine, but AKAIK, no oil temp guage. Are they complaining as much about oil temps getting over 200F?
Why is 200F bad? or 210F, 220F, 240..260? At what point does oil become less than what it was 10F cooler? How long at 260F does it take for the oil to have measurable degradation? How many miles/months does that translate to for the average driver?
All that...lol

The article I read on the bearing problem noted 300 degrees as point break for Nissan. I have to assume the 280 degree limp mode is just a bit of cushion. As far as general oil breakdown at what temp, I really am not that well versed in oil theory to make a call.
