Hopefully someone can answer this. I had a 2012 Jeep and a 2012 Dodge journey, both with the 3.6l engine and the recommended oil was 5W-30. I now have a 2013 Doddge Durango, same engine, and the recommended oil is now 5W-20. When I was at my dealer recently, I took a look at the 2014 Durang manual and it read, 5W-20 is the recommended oil, but you may use 5W-30 if 5W-20 is not available.
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.
