Here's an older chart. I'll see if I can find a more current one that has more oils tested. I think specific brand oils should have a chart of their own as well. But this gives an idea of the vastly different pour points, even among the same viscosities. Years ago I would have never thought they would be so different.

Will, isn't Brad Penn now Penn Grade? Or is it the other way around? Pretty sure that ranks right up there with other high end oils like Amsoil, Royal Purple, Red Line, Mobile, etc....
