Hello, I live up in the frozen tundras of Minnesota during the winter. We do get pretty hot summers though. So, should I run different oils in these different seasons?

For instance run 5w30 in winter and 0w30 in summer?

Also for the B58 engine should I bother with the 40 viscosity or just stick with the 30s?

Please keep in mind that I drive the car hard; I don't track it but I do drive it like it is meant to be driven.
