If one was to install a 100 degree thermostat in an engine and the cooling system was good enough the engine would run at 100 degrees. If the cooling system was insufficient then the engine would run at whatever temp the cooling system could maintain. This is evident with changing from 180 to 160 thermostat and the engine runs cooler. Try jamming a thermostat open and running it. If your cooling system is up to snuff the engine will never warm up. This is the reasoning for me wanting to lower the temp of the thermostat. Wondering if the engine will continue to run at a higher temp and overheat or run at the temp of the new thermostat. Fuel for thought
