On top of that question though, why is 20 degrees cooler a good idea? You want the engine to operate at the design temperature for greatest efficiency, don't you?

They advertise that it can get your engine to run up to 20 degrees cooler. Sounds like a good idea to me!
This is exactly what I was questioning.
When discussing stock engines, why would we want to lower the operating temperature? Aren't engines designed to optimally operate at a specific temperature range? And don't the engine designers select the thermostat that keeps the engine running in that temperature range? If the designers wanted the engine to operate at a lower temperature, wouldn't they simply spec a lower temp thermostat?
It seems to make much more sense to use products, such as Water Wetter in a heavily modified or custom built engine, where it may be more difficult to get the engine to run at the correct temperature.
So, yea. Unless there is a problem, why would one want to lower the operating temperature? Am I missing something?
