Exactly why I wonder if all of the "automobile" advice applies to marine
outboards. This is oil made for the auto industry where the "starting" range
is
0f or below to a normal operating temp of over 210f (what most auto
thermostats
run).
That is an operational range of 200 degrees or so.
Outboards seldom start below 70f and it is closer to 80 most of the time
here.
The thermostat is 120f.

30, 40,and 15W-40.... as you note... 30 will pump at -5F, 40 will pump
at 5F and if you boat at -25F, then 15W-40 is the oil for you.

See, in Jaxworld, water doesn't freeze until some temperature below
-25F and he is still boating. On a moments notice, he needs to start
the engine and pump that oil pressure up quickly so the bearings don't
grind and squeal... or whatever.

I don't know about ya'll, but at 5F, or below, I'm not boating. I'm
pulled up close to the fire, reading a good book, savoring a large
pot of fish stew, and a tall Guiness.....
