This isn't a question that has a simple answer. There are several variables, with driving habits/patterns the most significant. In 1996, I think the only engine available was the 5.7 L V-8, for both the 1500 and 2500, with either 2wd or 4x4. Personally, I have a 1999 suburban, 1500, 4x4, with the 5.7 L engine. Because I sometimes use this vehicle for towing a trailer for work, I use 80 PSI Michelin tires - stiffer ride, but higher mpg. Without the trailer, the best mpg I get is between 18 and 19 mpg on long distance trips and around 15.5 for daily driving. I rarely depress the accelerator more than 1/3 of the way (slow accelerations) and try to coast as much as possible when anticipating a stop. From what I've read, I'm getting above-average mpg for this vehicle. I keep the engine, chassis, & drivetrain well-maintained in order to maximize the life and performance of the car (the body, however, is usually dirty!).
Actually 96's have 3 different engine configurations: 5.7 gasoline, 7.4 gasoline and 6.5 diesel. All configs can be 2wd or 4wd, some can be 2500(3/4 ton) or 1500(1/2 ton). Needless to say, these will have varying mpgs. Mine is a 96 GMC K2500 Suburban with 4wd and a 7.4. City driving varies from 9 to 11 mugs depending on traffic. I get about 12 to 13 highway. Doubt my config can do any better.
