You won't be disappointed. I pull heavy everyday and not one problem. My dealer and I did a test on engine oil with my truck and found by switching to rotella T6 we actually got a lot better fuel mileage. Also ask your dealer about the extended oil change warranty, you can get buy 4 oil changes with filter change in the T6 for 240 bucks. That was about 30 bucks cheaper than I could do it myself for and use the mopar oil filter.
