Well, since the other thread was closed for some unknown reason, back onto why a SAE 30 actually cools better than say a 0w30.
Here's some bread-crumb evidence, sample A and B cool better than C D & E.
Now look at the formulation of the oils. Hmmmm, interesting.
Maybe later I show why SAE 30 cools better than any xW30.

substances with high cooling rates are good coolants and lubricants
