That seemed to be something of a consensus after the discussion of zinc
additives, or a lack thereof, a month or so ago.  I've been using Castrol
GTX 10w/50 (might be 15, thinking about it), and am considering changing
when I next change oil before I leave Phx for Seattle in early September.

I'm looking forward to someone taking me by the hand and saying, "Do it this
way" (and being correct about it, of course).
