What is the mileage you guys get from the latest trucks with LZ0 engine? My truck just drove around 1200 miles and came up with a mileage of 25 mpg. Mostly highways. Little disappointed but will watch.
I drive I95 between DC and Ashland at or below the speed limit. I normally get 30.5 if no traffic. Best was 36 (clear traffic) and worst was 26 (much stop and go). The Denali is almost a year old but only about 3800 miles on the odometer.
