I agree...if you are changing oil at every 5k miles on a daily, none of the full synthetic (F/S) oils are going to break down in there and become useless. F/S oils take a long time and a lot of use before they stop protecting.
I use LiquiMoly 5w40 now and used VW recommended; Castrol EDGE 5w40 for the first 120k miles.
My owner's Manual (N. America) states a F/S 5w40 VW 502.00 is to be used; but if 5w40 isn't available, then it is OK to use a 5w30 that is VW 502.00 approved.
