DEF refill
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?

If the tank runs dry on a GM product it will limit you to 5mph. Dont know about the other brands.
That's if you start the truck with the tank dry. If you run out while driving you can continue to drive normally until you shut the engine off.
no, reread your manual
