Apparently Mobil 1 and Dexos Gen2 are not the same. I have asked for 'spider' chart comparison and have been told they are working on it. I believe Mobil 1 will have an edge in some area(s) over new Dexos.
Like was said before 40 cents isn't going to get you to Mobil 1.
It will be interesting when (if) I hear from them. As a recent purchaser of a 2016 Impala and a long time user of Mobil 1 - I am more than a little curious. Especially now that I own a 3.6L V-6
