I personally have gotten into the habit of changing to synthetic motor oil during the winter months. I live in Colorado where it can get cold although not as bad as some places. I have seen temperatures as low as 28 below (no wind chill factor included) and it often gets 15 or 19 below some nights in the wintertime. Some winters are worse then others.
I just feel that there is no way a person can get around the fact that synthetic motor oil (everything else being the same) is going to flow better in extreme cold then conventional motor oil. There is bound to be less wear with the synthetic and the car or truck will start more easily. I like to use either Mobil 1 0W-30 or 5W-30 in the winter. I have a Saturn Ion and 5W-30 oil is preferred but 0W-30 can be used in the wintertime and 10W-30 is allowed in hot weather if 5W-30 is not available. If I had a Honda or Ford vehicle I would use 5W-20 synthetic.
In the warmer months I like to use Chevron, Halvoline, or Pennzoil conventional motor oil because I like to do regular oil changes. I recently used Valvoline conventional oil however because I was doing an Auto-RX cleaning. I think I will use Valvoline for the rinse phrase also. But normally I use Chevron, Halvoline, or Pennzoil.
