15,000 mile oil change recommended?

As far as I can tell it's straight dino oil 15W-40....This truck does have the 15,000 mile oil change interval..States if you use a synthetic oil, make sure it meets Cummins specs.

The oil from Cummins is 5-40 Synthetic Rotella. Original fill!

I didn't see that information, but it works for me...cool:)

Stuart Miller Regional Training Mgr. from Chrysler held a walk around with a 13 Ram 3500 single rear wheel SB in Pahrump at the first of the month. I pulled the dipstick and noticed it was very clean. That is when he said the oil was Rotella 5-40 Synthetic factory fill.

So there goes the theory of waiting X number of miles before running synthetic.

At 2K I started running AMZ/OIL 100% synthetic 15-40.

I drain my oil overnight on my 11 HO Ram and after oil change I start it and check level and the oil is black.

This is all good news on the 13 Rams!

I was hoping it would look clean. Makes me wonder if you could use the non LE oil?

I'm certain you still have to use a API CJ4 oil to protect the DPF.

That makes sense!

Why would the oil be black, the 2013 3500 is using DEF no more reason to have the third injection event to reduce nasty tailpipe emissions. This is what made the oil black in pre DEF Cummins powered Rams, that fuel wasting third event.

The '13 still have to regen to burn the soot collected in the DPF. The use of DEF eliminates NOX in the exhaust which also helps reduce soot production by allowing less EGR volume but does not eliminate soot produced by the combustion process.

From the 2010 and 2012 models, once you had an oil change, in just a couple hundred miles or so, the oil looked "dirty/black". I had almost 1,000 miles on my truck when I checked yesterday and the oil is not dirty looking it still looks very clean. There is a difference in how much cleaner the oil now looks in the 13 compared to my 10 and 12 after the above stated mileage.

I would have thought for sure that they would have used the Valvoline Premium Blue Extreme full synthetic 5W-40, if indeed they are going that route. (factory synthetic fill).

Shoot, I buy this from the Cummins shop in Sioux Falls. All of the Cummins dealers in my area (Minot, Grand Forks, Sioux Falls, Omaha) stock it.

Guess the endorsed and recommended by Cummins on the bottle does not mean as much as it used to. Still, a very, very good oil for diesels.
