I am a subscriber to Consumer Reports and have come to trust their
findings, perhaps mistakenly to some. Still, they have no agenda
(i.e., advertisers, corporate interests, etc.) other than to protect
the consumer. That said, on to synthetic oil.
According to Consumer Reports under normal daily driving conditions
there is no appreciable difference between it and regular oil. That
is, oil is almost never subjected to the stresses that manufacturers
cite as making their oils superior to traditional oil. Of course, this
would not hold true for racing applications. But under normal driving
conditions with proper oil & filter changes, regular oil is just as
effective as synthetic oil and, according to CR, provides no
significant difference except in your wallet.
