I'm looking at a 2011 silverado with the 5.3 in it. Does anyone have one that can tell me what the fuel mileage is?
I drive that exact truck, ext cab Z-71 4WD. Overall, in town and on the road it averages 17.5 mpg.
Just hwy, probably better. Probably a bit less pulling a trailer.
Good truck; I really like mine.
2WD may give slightly higher mileage, probably has different gear ratio.
