I data log EVERYTHING on my G37...
In looking at the data and doing some quick math, here is an average temp increase from ambient temp:
• Engine coolant temp increases about 32F/min (18C/min) under light load < 3500 RPM
(until the thermostat start to open, then it levels off)
• Engine oil temp increases about 14F/min (8C/min) under light load < 3500 RPM
(without factory oil cooler)
Roughly right, on a 80F morning, it should take about 4-5 minutes (( 140-80) / 14) before the oil temp gauge starts to move.
And at a 60F morning, ((140-60)/14) it should take about 5-6 minutes for the gauge to move.
Is this accurate to what you have seen?
