Porsche engineers had used the hotter thermostat to help burn off water in the oil with the idea the cars would go 15,000 miles on an oil change. In my opinion that is a bad idea. The other and the main reason is the hotter engine made it easier for the car to pass U.S. emissions. If I wanted to be green I would own a Nissan Leaf.

If burning off water was the purpose of the hotter thermostat, then running a 160F stat would show oil degradation is a used oil analysis; but in fact the oil does not show any signs of water build up and the UOA's actually indicate the oil is doing better because of the lower coolant temperatures.................
