Following advice I've read from Hartech; I bought a low temperature thermostat along with replacement coolant.
I also decided to do an oil change with Millers 10w50 Nano.
Nothing better than spending a Saturday afternoon in the garage.
Old thermo with new

Oil temperature is markedly down from mid 90s to mid 80s on the gauge.
Millers Nano is almost as black new as the used oil I dumped :?

I don't know if it's my imagination but the engine sounds quieter on tick over.
An afternoon well spent I think.
