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...

With my 06 Cummins it was shipped with Valvoline Premium Blue and all I ever used. I would be surprised if they ship with synthetic now but could be wrong. I thought synthetic wasn't recommended during break-in even though the Cummins can be worked right away. Both Cummins and Blackstone said no reason to change oil earlier than 7500.
