Synthetic will help. These conditions are where the benefits are best. It
is not a cure all and some common sense still has to prevail. When these
conditions prevail, it is not only the Vanagon engine that suffers. You
would be amazed at the number of Hondas and Toyotas that get damaged from
this weather and impatient drivers. My favorite is the cam shaft seals
getting pushed out. 15w-50 is still a very heavy oil for most modern
engines. Below 20F you have to be a bit careful. I have used it down to
-4F in Vermont one year but I do not live there. My take me to work
vehicles get the Mobil 1 0w-40.

Anyone know if synthetic oil would help here?  Mobil-1, even the
"heavy" 15W-50 formulation, flows much better at cold temperatures
than conventional oil.  Should flow better with less backpressure even
when cold.
