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...

Electronic sensors throughout the drivetrain send information about engine revolutions, temperature and driving time and other factors to the car's computer. The data is run through a mathematical algorithm that predicts when the oil will begin to degrade. The light comes on well in advance, giving the owner time to get the car serviced.
I follow the oil life monitor..But...Change it when it shows around 20%. And or, I also change it it gets around 8000 miles and still shows lots of % life left...kind of a combination between new and old school.
Others change oil at 0% while others still stick to the old 3000 mile rule..
I use the % left as a guide, but change it when it's convenient for me. I'm usually slightly conservative though, usually dumping the oil at about 5000 miles or so, even though my truck uses 0w40 synthetic.
