whatcha think ?
Not uncommon. The OEM thermostat is not open until around 190F or so, and normal coolant temps in the 210F+ range are common. If you could test various areas of the engine with a non contact pyrometer, you would find local "hot spots" that are much higher. Your oil is also even hotter than the coolant by around 15F.

This is why a 160F replacement thermostat is an interesting upgrade.....
