Try this test.
Cruise on the highway in 6th gear at 70mph. Log for 120 seconds. Now do the same in 5th gear. Then 4th. Then 3rd.
Watch how the oil temp equilibrium goes up exponentialy as RPM goes up linearly. Feel free to adjust vehicle speed to get linear RPM steps, if you prefer, and graph out the data points.
