I do not think automobile oil specs in the 1980's and 1990's were written
considering the better cold flow characteristics of synthetics.

A good synthetic 10w30, 10w40, or even 15w50 will probably work fine for
winter in most of the USA.  I the extreme northern regions of the USA or
Canada you might go with 5w30. I run Amsoil synthetic 10w40 or 10w30 as my
winter oil.

I know some people that run 5w30 synthetic year round because they feel
that the thinner oil offers the benefit of getting oil moving sooner in the
summer as well.
