Frankly, the label "synthetic" is pretty meaningless. No reason to believe you are getting anything special or better than a good dino oil. Anyone could slap any label on any SM spec oil and call it synthetic. When you buy a branded oil, you know what you are getting. Some are good in cold, some maybe clean a little better, etc.
I'd say, ok, use ORiley's oil without worry, but don't expect miracles over a good dino.
