The factory spec it 195 degrees. It is at that point that the engine computer is expecting it to run, and it will be most efficient. That assumes that the engine is equipped with a 195 degree thermostat to get it to run at that temperature. I have a 1986 that has no thermostat and it commonly runs at 140 degrees, probably not warm enough to suit the computer.
