Most engine wear occurs when the engine is started after a cold soak and the oil had drained down to the oil pan. When the engine is first turned over, the only lubrication present is the oil film remaining on friction surfaces until the oil pump starts circulating oil.

I use synthetic oil in 2 out of 4 cars. Obviously, I don't have anything against synthetic oil since I use it myself. The part I disagree on is that using synthetic saves money when following the factory recommended oil change intervals.
