What Is The Optimum Engine Oil Temperature? - Hot Rod Network
I'm not boosted and have no additional cooling. So, how Nissan designed it. City driving I hit 220 and it doesn't go any higher. Seems to agree with the article. 212 seems to be a popular temp (boiling point for water) but as article mentions, there are other impurities that should be burned off. I'm not an oil guy, but I don't see any articles saying 200 and below is a good thing.
