Subzero temperature starting.

[Danton J.A. Cardoso]

Overnight tonight here in NE Missouri it is going to be around -5 or
lesser for the temperature.  Unfortunately, my A4 is parked outside,
but at least it is under a carport.  The starting ritual I do in
temperatures like this is shove the clutch in, hit the gas a 1/4 way
and fire it up.  Now, I know the traditional way is wait a few
seconds, and drive off, which I do shifting at 2000 rpm.  However, in
the past there are times I have had let it idle for about 10-15
minutes, or until the water temperature gauge is reading two or three
notches above cold, or even to normal temperature.  Should I do this,
or do the drive off the traditional way?  108K on the odometer Castrol
Syn-blend in the crankcase, 5W30.

Thanks,
