Dan, take it from a long time DEF user. The very last thing one needs to worry about in truck ownership is the amount of DEF it uses. Worry about rain, how long the wiper blades last, are the headlights aimed correctly, is Junior going to get a scholarship....I could go on and on. You're in the neighborhood of a penny per mile. Your insurance costs ten times that. Your oil and filter changes are four times that. See where this is headed? Buy it and drive it.
