But at really high temperatures it will actually transfer heat better into surrounding.

5w-40 also seems to heat up a good bit faster than the FE 0w-30 right? or am i imagining? the dealer FE stuff took forever to get to full temp. |
Yes. Bcs. resistance. But that doesn't mean it is more economical. FE is thinner during warm up=less heat=lower consumption. Problem with these FE oils is when you push car.
