This link to a BITOG thread discussing MRV and CCS is relevant here although I'm still trying to digest it. From what I gather from reading it kinematic viscosity is irrelevant at cold temperatures. https://www.bobistheoilguy.com/forum...Number=1836257 |

But I want to add that there is the technical possibility that a 5W CAN (albeit unlikely) have a lower cP than 0W because the weights are dictated by a maximum cP at a given temperature. So, if a 5W just happens to have a 50,000 cP at -40°C versus a 0W oil at 55,000 cP at -40°C. But yes, the cold crank and pump is more important than the kinematic viscosity in the cold, but kinematic is still important. Oil still needs to be able to flow and seep around parts in the engine.
