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.
