Two things that have surprised me about our cars:
• Our engine oil pressure is VERY high!
More than 120 psi on a cold start (well, In Toronto during December)
With engine oil at or above 80C/176F we still have 90+ psi at high engine RPM

• The differential oil can heat up 3C/5F during a single 0-60 mph run. (and that was during a 0C / 32F day)

With the G37 Sport Sedan being about 500 lbs heavier, I suspect the diff oil heats up quick than the ~3200 lbs 370z.
Optimiser and old guy like this.
