    2001 Silverado with 4.8L V-8, automatic, 2WD, no performance mods - it's all completely stock.

    I do almost nothing but city driving and get 13.5 mpg. If i take a road trip, say Dallas to Houston, I'll get 16.5 mpg if it's all highway.

    Consider, I do have the added weight of a bed liner, loaded tool box and over-sized all-terrain tires.

    2013 ecsb 5.3 5" lift 285/65/18, borla exhaust, airaid mit, blackbear tune driving is mostly country roads, 55 mph speed limits and stop signs every 3 miles, and about 15% city driving. These numbers start at the bottom as e85, then switched back to gas. Keeping a lighter foot makes about a 1 mpg difference

    Airaid. Borla. Blackbear. RCX.
