Just drove from Ohio to Leadville, CO pulling my Rockwood Mini Lite Camper with my 2013 T-reg. Loaded it weighs around 3,800 lbs. I topped off the AdBlu and have driven 1,800 miles. I had to climb from Denver to Eisenhower tunnel. Running 2,500 to 3,000 RPM going up and down the other side. Temp went from 220 to 230 or 235 several times. When I got close to Leadville I got a AdBlu in 1,000 miles. The next time i start it says 900. I have never, never gone through AdBlu this fast in around the 70,000 miles I've driven it. Did the heat and high RPM cause the usage? When you get a warning how much is left in the tank?
