cars need to start becoming concerned?I assume additives are always
included with fuel at any season but if temps reach -20c say could there
be problems?
My comments are prompted by the contents of dedicated weather sites
which are now indicating prolonged and severe cold.

yeah, -20 will give problems- stick half a gallon of unleaded into a
full tank of derv to unwax it and you will be fine
