Any wonder why at 0-40 engines might use oil ?

and what about volatily (evaporation) of certain oils and the many other variables that can be a contributor to oil usage in an engine?? viscosity is rarely a reason for oil usage in engines. That chart (if it is even accurate) tells nothing relevant to oil consumption issues.

Another thing most people don't understand is that the oil temperature is measured at one of it's coolest points in it's circulation. Not many can comprehend how hot the oil is in the hottest part of the engine. The oil's ability to clean, lubricate and seal is not dependant on the temperature displayed on you gauge, but at the maximum temperature the oil reaches during it's cycle. It doesn't matter how cool it gets during the rest of it's flow.....the damage is done.

Gee, thanks for telling us, Capt. Obvious!

The "zero" in 0-40 would only apply at start up under certain conditions. At that point this chart suggests the oil is thinner than water. I find the whole thing interesting and intended no global implications. I will repeat, however, that my car is using much less oil at 5-40 than it did at 0-40.
