Won't fresh oil with no water in it flush out some condensation in the OS? You have to change it anyway so it won't hurt.

My method to thaw out the OS will only be used a few days out of the year. How much engine wear will that be?? Starting up and driving is the correct thing to do but at 0 deg or less your certain to have a blocked OS if you do short trips. I've had this happen every winter, and learned my lesson. I guess another alternative would be to stay home or if you're really concerned about the engine wear at start up you can drive five minutes to a coffee shop and sit for 30 minutes or so. Both beat seeing white smoke and an engine covered in oil.
