I have 5400 miles on the 2013 Ram 3500 and its time to refill the DEF tank. Mostly easy driving and minimal towing so far. How many miles are you guys getting on a tank?
My 13 CTD 2500 made it 2800 miles on 5 gal of DEF so far. Hopefully the range will increase, I am having issues with a nox sensor(on back order), not sure if that is gonna make a differncee or not.
