I still recall years ago on a Porsche forum some owners were voicing the opinion 0w-40 oil (the factory fill) was *too thin*. And switched to 5w-40 oil. An oil viscosity which Porsche happened to approve of but not at temperatures below -17F (-25C). Some owners learned the hard way how important oil flow at cold temperatures is when their car engines suffered cylinder/piston damage from insufficient oil due to used 5w-40 oil.

When you're talking about driving cars below NEGATIVE 17F, you have to realize your point is becoming moot.
