Its best to stay with the 5W-20 weight as called out in the owner's manual.
The cam phaser (part of the VVT system) depends on oil pressure to do its job.
-if the operation is out of the range, it will throw error codes and could potentially put the vehicle into "limp home" mode
PS: any 3.6, 5.7, 6.4 engine has VVT - and each of these engines have their specific weights of oil recommended by FCA
3.6L V6 - 5W-20 [MS-6395 FCA spec]
5.7L V8 - 5W-20 [MS-6395 FCA spec]
6.4L V8 - 0W-40 [MS-12633 FCA spec]
6.2L V8 - 0W-40 [MS-12633 FCA spec]
