I am having a bit on analysis paralysis on the oil for my next oil change. I am leaning towards the Duron UHP 10w40 over the 0w40 for my 2014 Ram with the 6.7 Cummins. I live in northern Canada so the -45 pour point is an actual consideration for me. If the price was comparable is the 0w40 that much better looking at the chart below? I was running Rotella 5w40 but the dealer I was going to has jacked their pricing so much that I am now going to just do my own in the shop at work.
