While true, then I assume it'd also be true with other cars that don't have an oil temp guage there for the driver to see.
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
