At 5 minutes the needle was between the second and third line, the third being the 180 degree line. At 6 minutes the engine was up to full operating temperature.

At higher ambient temperatures and/or higher speeds the temperature would have risen faster.

If you run a low temperature thermostat in the mistaken belief that it will reduce engine overheating (see Low Temp Thermostats: What’s the Advantage? | Tuner University), then the warm-up temperature will be longer and engine wear will be higher.
The logic of #8 sold me.
