Do an oil analysis of your own oil and tell me it's 0% gasoline contamination. Gasoline contamination contributes to oil vapor in the crankcase, directly affecting valve stem deposits.

VWUSA is making stuff up because they for years opted to not sell US cars with the dual PFI/DI injection system that is used in the European market.
Top tier gas has nothing to do with fuel solution nor will it prevent IVD. Choice of oil and the PCV have an impact.
