Conditions in bearings do seem miraculous. In horizontal Jowett engines when run for modest mileage on clean oil, the only evidence of rubbing contact is often at the little loaded bottom of the main bearings where no film on initial movement.
With the much higher psi loading films are very thin in modern cars and hence filters and additive oils more important.
