Oil... how does it work? [split]

You’re a troll :rofl

It has not been explained why SAE rating of being low (fluid) viscosity at a low number and high (thick) viscosity at a high number for the same oil tested at two temperature ranges (0, or fluid at 32deg, and 50, or thick at 210deg) does not match real world observations.

If oil thickens up as it gets colder (which it does) SAE rating should follow that and display it as a high (thick) number as first number and a lower (thinner) number as the second.

Where was that explained again “400 times”?
