Quote: Yes 160* is too cold a stat it should be at least 180* to get the engine up to a good efficient operating temp.
Not to start any arguments or anything, but how, or what determines "efficient operating temp."? I've been using a 160* stat for over 40 years, with no adverse effects on the engine or oil. Why should I change if what I have works for me?
