I tend to disagree with the analogy of water on your kitchen floor verses moisture in your
oil. Water on your kitchen floor evaporates and doesn't require temperatures in excess of boiling point because it's an open environment. Your oiling system in your engine is an enclosed environment and not exposed to outside air. It does require temperatures in excess of boiling (212 degrees) in order to burn off the contaminants.
This just supports the need to have a thermostat in your oiling system if you want to run an
oil cooler.
