Any 13' Ram DEF MPG yet?
Just stopped by dealer and checked out a new'13 Ram 2500 4x4 Laramie Diesel and was wondering if anyone got theirs yet? How are the MPG's compared to the last few years? Any other thoughts? Thank...

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.
NC,
Do you plan on following the OLM to determine when to change the oil?
NOPE!! I get 3 years of free oil changes...it would be RARE for me to put 15,000 miles on my truck in 1 year...SOOOOOO, I'll probably take advantage of the free oil changes and get one every 6 months,ie (work it to where it's 2 a year). "IF" I were going by the OLM, then when it stated, "oil change due", then I would change the oil...I beleive 15,000 miles is a "best case" driving/towing scenario and the OLM actually allows you to drive 15,000 miles before you get the message to change the oil.
