Tom, I have used M1 15w50 and Rotella 15w40 on long trips and in the
summer. Wintertime is M1 10w30/40 or Rotella 5w40. The 5w40 tests as
better oil than the 10w30/40 but not as good as the 15w50. Up there in
the great white north, you should be good with 10w30. I would only run
5w30 when it was butt cold, and the 10w30 the rest of the time..
