Having read the article by Dr. Haas, the "oil bible" and many other oil articles....
If all Synthetic 30 weight oils fall into the same vis. category at 200F, regardless of the cold weight rating. Wouldn't you always want the oil with the lowest "winter" weight possible? eg. 0w-30 ? Why would you ever choose a 10w oil? (Unless maybe the abient temps were 90F regularly)
I cosntantly read "you should try 5w or 10w" etc. and its not making much sense to me?
