I just arrived in TX after 3 days of driving. First 3 tanks of gas @ 70 - 75 MPH I got 30.2 - 30.4 MPG. The second day I took route 130 South of Dallas. About 100 miles and the speed limit was 80 for the first segment and 85 for the last segment. I did 82 to 87 mph most of the way. The mileage dropped to 25.6. Had just over 1,000 miles on the odo. when I left and the van was packed pretty full. I am satisfied. Seems slightly better that my 2014 T & C.
