So what you are expounding is studies that have been done maybe 20, 30 or more years ago. That's about as relevant as a flintlock is to an AR15.
Fluid viscosities have become much thinner, engines run 15, 20 25 degrees hotter, fuel economy considerations have completely changed engineering requirements.
One of the great rules of the internet is that if you keep repeating the same old drivel long enough, it becomes the TRUTH.
Bring me some data from the last 5 years and I will reconsider my position.
