So, my question is: can I use 5W-30 in my 2013 Durango, and why is Chrysler switching back and forth on this issue?
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. OM Link
