2015 Ram with Cummins oil change interval
With my 2006 Ram with Cummins I just changed the oil every 7500 miles. With the 2015 I have on order there is an oil life gauge. So does this actually analyze the oil or just go by miles? Does is vary...

Factory fill is with 15W40 Synthetic.
It's 5-40 since they don't know where the truck will end up. They only recommend the 5-40 after the initial fill if you live in a very cold environment.
