All oil gets dirty at the same rate, but synthetics have more advantages than
just longer life.  They provide better lubrication all the time, making the
engine run smoother, cooler, stronger, and last longer.  The measurable result
is a small percentage difference, but it is real.  And Synthetics are true
multi-weights.  Regular multi-weight oil starts out as one viscosity.  20w50
regular starts as 20w, and polymers are added to give better resistance to
heat breakdown.  The polymers begin breaking down immediately with use, so you
gradually lose the protection of the upper heat range.
