Hi I note that Mobil no longer states pour point low temperature values for some of its oils. Is there are any correlation between the 2 systems for representing low temperature flow/pumpability ? Below are some examples from the Australian website. How is the MRV value to be interpreted ? Mobil 1 5w50 MRV at -35ºC 27653 Pour Point temp ? Mobil 1 15w50 MRV at -40ºC 12188 Pour Point temp ? Mobil 1 0w40 MRV at -40ºC 26242 Pour Point temp ?
