Current Mopar Oil is not Mobil 1 or any other Mobil product.
Until the bankruptcy/bailout period around 2008/2009, Mobil 1 was the recommend factory fill for SRT performance model engines at Chrysler. With the bankruptcy looming and before FIAT stepped in, Mobil would not extend product on credit anymore to Chrysler and became "persona non Grata" later down the road. With FIAT taking over Shell/Pennzoil became the recommended branding with Chrysler.
With the MS-6395 spec coming out and eventually evolving into a 2 year certification process, Mobil has never been in a hurry to get MS-395 certification. MS-6395 is not a high hurdle anyways if Valvoline conventional can get it.
