My '81 starts down to zero and below with 10W30 oil.  Last
winter, my 911 sat outside at a ski area for three days
around 5 degrees and would hardly turn over with 20W50--
and it has a BIG battery.

There is a BIG difference below 15 or 20 degrees between
10W30 and 20W50!  So before you crawl around checking the
starter wires, etc, check your battery voltage and put in
winter oil.
