Any help is appreciated.

Your owner's manual for the 2013 Durango states 5w-20 recommended, not mandatory. And further states:

"NOTE: SAE 5W-30 engine oil approved to Fiat 9.55535-S1
or Fiat 9.55535-S3 may be used when SAE 5W-20 engine
oil meeting MS- 6395 is not available."

So sounds like the same thing as 2014. Most owners manuals for most standard cars state the range and types etc recommended and other options.
