My drive to work today in my 2.3i is 7 miles. So starts to rise at about 3 miles.
It will just about get to about 85 by 7 miles . Summer it will go above 100.
But at least once a week i like to get it above 100.
The oil temperature thing has made me very much aware of how much abuse my previous cars suffered with only water temp gauges!
I thought i was treating them well!
My 35i is blowing warm air from the heater in around 200m! As for oil temp, that depends on a multitude of factors;
Ambient temp
Driving Style
Age of oil
Condition of engine
Efficiency of oil cooler
