It's near zero F. these mornings in NH. If anyone would like to see the data I'll start from cold tomorrow morning and scan coolant temperature and oil temperature on my way into work. Then I'll post the graphs and you can see what happens when.
Please note that this will pain me greatly. Ilsa prefers to hibernate for the Winter but she'll do it in the interest of furthering the collective knowledge. Ask nicely.
(I've done this before, but didn't save the graphs. There are lots of interesting data points.)
