Just drove my daughters stuff up to move in college today for senior year. Up thru the adirondack mountains in upstate NY. My previous JLUR w/ 3.6L averaged 18.1 on the sage exact trip. 1st trip with the 392 and got a whopping 20.9! How can that be??? Not even 1/4 of a tank 110 miles. WTF? Not near as much downshifting as the V6 so I figured the torque on the V8 helped? Up the mountains and down. Averaged 55mph, very humid for upstate NY today and 88 degrees. Running 91 octane non-ethanol. Rte 28 and 30 if anyone knows where that is.
