Default Re: Thermostat - Which One?

Dare I ask?
How is the engine affected by running too cool. I know SoCal never really qualifies as cold, but my Motometer never even regiseters a temp by the time I have driven to work on winter days. I assume, therefore, that the engine is running cool. I understand that there is more wear on engine parts during cold starts when the oil isn't up to temp or hasn't reached bearings etc. But after the engine is running why is it important to have a coolant temp of 160 - 180?
I've been driving my little coupe to work all week and just mentioned to my wife last night how much the car seems to love cold mornings. (The trans oil is thicker and so the car is quieter and the shifts are quicker). The motor has plenty of power warm or cold.
