This will also extend the life of your engine if you like to drive hard.

Safe mode is much higher than 200 degrees. Think about this- the oil needs to get higher than 212 degrees just to boil off any condensation. 200-220 is ok on this car. You'll see power loss from IATs, not oil temp. And you got boned on the oil cooler. First, you paid WAY too much for the unit and install, especially if it's the Nismo version without a thermostat. Labor was especially rapey. And if the oil is at 160 on the freeway, it's too cold. Cold oil is as bad as hot oil.
