My truck's:
2016 4.3L CC 4x4 SB - I can't use lifetime average as it spent time idling that the 6.2 did not. Best 500km (~300 miles) fuel econ without idling = 19.1-19.2mpg - Work truck which was replaced last June with a Traverse.
2017 6.2 Denali CC 4x4 SB - Using same criteria, best 300 miles over the same roads, weather conditions, etc = 23.5mpg
Previous 2014 6.2 Denali CC 4x4 SB (Same criteria) = 21.75mpg - I attribute this to the A6 vs A8, traded this truck for the 2017 @ 60,000 miles.
Edit: Regardless, I spend more time towing and hauling with my 6.2 than my work truck, so I compared empty numbers. I can't even imagine trying to tow 1000lbs with the 4.3, let alone the 9000+ I have on many occasions with my 6.2s.
