You mentioned that there is no scientific, controlled studys on how and when the overheating happens, how about everytime I drive my car. If you were having this issue with your car, that would be all the scientific evidence you would need. You need to study up on engine oils an see how the oil begins to break down when it is overheated to the 240-250 range. At this point, at whatever percent of breakdown, it is lubricating the engine less and less, which leads to engine wear and internal problems.
