Went to see family over Thanskgiving and took the Charger. Left the house with 870 miles on the clock from the Atlanta area heading to High Point NC. Most of the trip was interstate up I-85. As soon as I hit the interstate, I reset the trip MPG readout. Totally stock 2019 RT with a BT catch can installed. Tires at 35 psi cold. Ran about 5 over the posted limted when possible, (there were lots of "other" Chargers out as well, with light bars). I was not expecting this. Left with 3/4 tank, refilled at 1/4 and the range was 415 miles. Next tank I filled just shortly after the low fuel light came on and the range was 485. All in all went about 900 miles.
