In cold weather and short distances that is normal for your car. During the warmer weather (above freezing) the white gunk normally doesn't appear.

If it were my car I would take it for a 30/45 minute drive instead of changing the oil. I run Mobil 1 0W40 year round and only have the white gunk problems during the freezing weather and short trips which don't occur very often for me since I have a 60 minute commute to work.
