I am using Chevron RYKON 32 and have not had any problems with it. I think the
32 refers to the weight, and there is a "16" as well that might be better for
the sub-zero climates. I have noticed my steering being a little sluggish when
the temp was near zero. It seemed to warm up quickly though.

As for changing the oil, it is so much cheaper you can change it all you want -
but I would guess oil life is the same as for the pentosin. Probably ought to
change it every 30K or so.
