My assumption is that DEF fluid lasted like 15-20 tanks of fuel. My truck has to be filled up every 5-6 tanks of fuel. 3.? gallons. I do pull a heavy enclosed trailer a lot on the highway, and drive high speeds, maybe that has to do with it. No one has ever answered why. So I am complaining about it here.
