I rented a 2015 Durango for a week out west - and 1200 miles into my trip (and a few thousand miles since its last oil change, from what I could tell) I checked the oil. 1-1/2 inches Above the full line. 3.6 PentaStar engine. now that was a dilemma! I was way up in the mountains with no access to tools or anyone that could assist... what does one do?
