>5W-50 is correct.  I have never encountered a problem with oil pressure, at
least as indicated by a flickering light at low rpms.  This includes a
number of desert crossings in the summer (Mojave and Anza Borrego) with air
temperatures of  +110 F.

pressure due to thin oil.  Still, I use this oil year round and get easy
starts in the winter and seem to get good summer protection - at least from
a standpoint of oil consumption.  Would welcome additional feedback.  Will
post info later this summer after the switch.
