The ability of engine oils to provide hydrodynamic lubrication under operating conditions is essential. Such lubrication occurs at very high shear rates -- often well in excess of the current SAE J300 specification of one million reciprocal seconds.This paper presents data obtained for shear rates beginning as low as two hundred thousand to above five million reciprocal seconds as well as the technique developed to obtain these shear rates.
