The most expensive ones!  J/K, but not really.  Royal Purple, Amsoil, and Mobil 1 are the most preferred, but Motorcraft, Castrol, and Valvoline are very good also.  At least one vote for Pennzoil Ultra:

Look for the MSDS for these oils in the weight you are running for a direct comparison.  The NOACK Volatility numbers are key.  Fuel dilution in GDI engines is a known problem, but the 5K interval should keep you out of trouble.

Had appt today at the Dealer,spotted some excess oil around the rear valve cover gasket and the service advisor ordered a new updated valve cover and pcv,but turned out to be the wrong part,he showed me the updated version and it was black and made of hard plastic and steel and was alot heavier compared to the aluminuim oem,will have to make another appt,will keep you updated.

Awesome info, would love to know if that's a warranty item. I wonder if the new parts will help the blow-by build up.
