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...

The oil life monitors on our Rams in the Arctic actually seem slow compared to engine hours, but I haven't done any oil samples to disprove its validity/.
These trucks idle ALOT at sub zero temps, some run 24/7. No load driving conditions, 35mph max. We change at 400 hours regardless of meter readings and it takes about 2 oil changes to get to zero on the oil life meter. Maybe the new engines are very efficient with preserving oil quality, dunno, but for example, my truck has about the most road miles and least idling in the fleet and I average about 4mpeh (miles per engine hour).
If I was going to trust the oil life meter, I'd run a blackstone test or 2 for comparison.
