Has anyone definitively proved whether hot oil is thinner than cold. One just assumed it was, but when you think of the purpose of the various elements in multigrade, which many of us use, (yes, I know Lehmans were originally run with 30w single grade, so don't bother repeating it), then it is even possible, if they do what they claim to, the oil might get thicker when it gets hot..? I never thought much about that.

This suggests that the above is not correct, and the assumption that cold oil, even a multigrade, is thicker when cold, is in fact correct.
Bugger, I was hoping not.
