Yes, I concur.......to an extent. I don't know how many -0 degree days you've experienced in Eastern Wa......But I'll tell you, in New York, when we get a " Polar Express" come thru in the winter, it can get down to -5 without the wind chill effect. That 5W30 flows good until you hit 5 degrees. Even using the 0W20, my Honda is not happy at those temps. Let her warm up good before I leave to get all the juices flowing. Cylinder head valves clackin away, shakin and carrying on ( I''d do the same too if I were out in the cold all night . LOL ).........So, for ME, a more moderate temperature climate, I wold go for the 5W30. That's just MY personal experience.
