I daily drive a turbo car of similar configuration, and have both coolant and oil temp sensors.  |
And I almost completely agree.
But what about track use?
I could tell that uphill 2 and 3er gear mid to high rpms are the highest temps on my car and are around 212f, (but I have a big oilcooler) and is a long uphill. Right after the uphill ends temp drops in seconds maybe a minute, to 200f
The couple of times that take the car to the track it get hotter but 225f
Note: those temps are peaks at the digital gauge.
Some times early to work oil only gets to 190f
