Agreed,this premise ignores a natural law. That all oil is thick when cold and thins as it heats.
If it were true, all the short trippers VVT engines would be running awful...because they all run with thick oil.

That is not true for a number of current production engines. In fact, temperatures affect oil viscosity far more than chosen grade. Do the variable cam timimg components stop working when operating these engines in cold climates?
