I would run a good quality, high ZDDP, mineral oil.
Valvoline VR-1 10W30 or Rotella T4 15w40, depending on how thick you want to go. I tend to go thicker as a car ages, and you live in a mild climate (I believe) so 15W40 should be fine.

It's got 1155ppm Zinc, a TBN of 9.2 and a nice slug of Moly at 57 ppm. Plus it has passed all the modern CK4 wear tests and anti-oxidation / deposit control tests.
