Use whatever you like, it won't hurt. Personally, I like M1 HM 10w-30 in mine.
If anyone attempts to admonish you for not using a Xw-20 oil, ask them to please explain the difference between the MDS systems on the 5.7L Hemi versus the 6.xL Hemi, because the 6.xL Hemi says to use 0w-40 oil. (Hint: there is no difference between the MDS systems except the engine in which they are installed.)
