Mobil 1 AFE 0W30 (SN/GF-5) used to have an impressive MRV of 13250 @ -40C and a pour point of -50C, so I bought some, not realizing I got the newer SP/GF-6A formula. I was very surprised to find out that the new version has a pour point of only -42C (-39C according to the MSDS) and no longer lists the MRV (obviously because its horrible, as it would be measured at almost its pour point). Can a 0W30 oil really perform well in the cold with such a pour point? Wouldn't one of the many 5W30 oils with a pour point around -50C and MRV in the 10000-14000 @-35 range perform better in terms of cold starting? Or is there something I am not seeing here?
