what oil to use

Yea I'm running 80 psi cold oil pressure, 60 psi hot with 10-30, and some mornings are pretty cool to be running 20w-50 up here. Car goes into storage in the winter but gets run whenever it warms up.

Oh yes, British Columbia. It is a little colder up there than it is here in Maryland. My car only holds about 10 psi more than yours hot and cold.
