I'm curious and would like to know:

I'm with ChrisKC; at these temperatures you might opt for a 0W / 30 multigrade available (a o) from Castrol. As a rule of a thumb in my Alfa Romeo days we used to keep 80 degrees centigrade as the minimal 'operational' oil temperature before we'd give a car the boot, which could take quite some time with those finned sumps.... So pre-warming up might be a good idea.
As with regard to warm gloves: Soldier Of Fortune sells those nice 1930-'s and 1940's RAF gloves.... haven't yet tried them at glacier temperatures but they do look the part http://www.sofmilitary.co.uk/raf-1933-fl...duct,19985
