Has the metallurgy improved today to the point where these engines are designed to run with longevity at the higher temps we are seeing? Are we applying old school oil temp knowledge to a modern engine that is built with components that withstand higher temps? I would assume 280 is dangerous, or Nissan would not have placed limp mode at this threshold. I would still worry about prolonged driving at 260 to 280 personally, and with the 90+ heat of summer coming, that worries me.
