I am a little confused about GC 0W-30. I have read posts that consider it to be a thick oil. 0W30, I believe should be thinner than a 5W-30 or a 10W-30, at least when it is cold. Is this a great oil for cold weather and cold starts (should be better than all 10W-30s and 5W-30s, viscosity wise?)? Being a bit thicker at operating temperatures shouldn't make a difference in the cold. Or am I missing something...
