There'd better be oil - under those conditions, the oil pressure gauge 
is pegged at 5 bar.  Hard to imagine "5w" isn't getting where it needs 
to be.  But at that time, I am not seeing motion on either coolant or 
oil temp gauges.  That comes a couple of miles up the road.

Interesting, sort of.  But coolant thermostats aren't "on/off" switches, 
they open gradually.  Also, at least with our engines, the "cold" juice 
from the radiator hits the t-stat before entering the engine, so if it 
is "too cold" only a little will get through at a time.
