I run it all year. Car is garaged and driven wherever the roads allow, including last week on a relatively warm January day. Oil pressure was good right away. I like that the carb bowl dries up so it takes some cranking to fill it, all the while oil pressure is building.

Here is a chart that backs up what Adam is saying. First column is 20w-50 oils and their pour ratings. Notice how not all 20w-50 oils are the same.
