My 04 ecsb with the 6.0 gets between 16-17 but the 00 rcsb w/ bolt on 5.3 and 4.10 gears gets a SOLID 20mpg. I'm loving goin over 400miles a tank and still having gas left over.

12 mpg on the fwy and 8 mpg on city streets. And that is GRANDMA driving too!! Never above 3K and not in boost. I'm scared to see what I'm gonna encounter when my foot starts getting heavier!

17 highway
13.5 city

On long highway trips have seen as high as 19.5 cruising at 65mph, any faster then 65 and it starts droping fast. 72mph is around 16.5-17mpg, 80mph is about 14mpg.

4.10 gears and AWD like to start drinking fuel once the rpm's climb.

Recently, I got just over 21 mpg on a trip to & from work. Driving like a grandpa. Average over the past 6 months is 16.6 mpg. Not too bad.

Right now I'm averaging 14.1 HWY 80% . LQ9 w 410's and awd. Its also 95 constantly every day and about 88 at night here. Hopefully when the temp starts dropping my air wolnt be used as much and better mileage will be in my future. Hoping to get my tune also so I should pick up mileage.
