you honestly feel the difference in oil, lowered the temperature? That the heavier weights transfered more heat outta the engine? (making sure i understand correctly)

 

speaking of oil weight, what do you guys think of the theory that thin oil will stay in the bearings better than thick. the wisdom has always been thicker oil in hot applications, that the thin oil would get crushed out of the high rev bearing(?) maybe the thinner oil would be easier to get in there, than the thick.
