Viscosity
At what temperature does 20W (winter) oil change to 50 SAE oil?

Serious question?
Viscosity is measured at 2 temps. 40C and 100C. So it acts lke a 20 at 40C (104F), the cold temp and at 100C (212F) it has thinned and is a 50. Thrre are molecules in the oil that physically change shape w temp to help the natural effects at work.

Now not so much..., are the centigrade temps used for French oil?

Oh, at 100C the oil acts like a straight SAE 50.
At 40C it acts like a straight SAE 20. It is still thinner at 100, there is no escaping heat.
