Straw-man arguments are your specialty, I see. I was extrapolating track usage temperatures to what we see in the 370Z under routine or spirited driving. Again, if you wish to reach temps of 240-260 under spirited driving and 220+ under normal conditions and change your oil every 7500 miles, enjoy! You are obviously misled if you believe this will not cause premature failure.
