Car craft did an article on oil. Viscosity breakdown is not a big problem anymore but synthetic is better in extreme cold and extreme heat.

This article is 14 years old, SJ oil ratings. Lots of oil improvments since then.

Its -24*F with wind chills over -46* wind chills right now, I am sure the synthetc cars outside are starting better.
