This is the flip-side to the oil pressure concern: oil FLOW.  Oil
pressure keeps the bearing surfaces from becoming more intimate than
intended.  Oil flow carries away heat and contaminants.  Both are
necessary for engine longevity, but only pressure can be measured in a
practical manner.  Synthetic oils are much better at meeting both
requirements than conventional oils.
