I've seen a number of adverts for thermostats that run an engine cooler than the manufacturer's orginal. Why do this?
As far as I recall (from long ago thermodynamics lectures), the higher the engine temperature the more efficient (power and fuel) it will be.
Have I misremembered or is there another benefit in running an engine cool that outweighs this?
