What oil?

A 10w30 synthetic that meets ACEA A1/A5, which is a far more stringent spec than the API. Mobil 1 or Castrol Syntec come to mind. Zinc is history, so we must rely on the best base oil possible (remember that zinc only has an effect on metal-to-metal contact, if the oil works properly, zinc doesn't matter).

Sooner or later, everybody will probably pipe up with their personal preference. I run Mobil 1 10w 30 in everything and have never had a problem.
