Not sure if all the 6.4 owners know this. The 6.4 takes 0w-40. Currently there is only one oil besides the mopar brand that meets Rams specs of MS 12633, and thats Penzoil Ultra. There are other 0w-40's out there but they dont meet Rams standards.
Interesting and thanks for the info. I just bought some at Walmart and I'm pretty sure that wasn't the brand. I'm wondering if it really is any different or if it's just a matter of testing/clerical stuff before Ram will approve it.
