* Engine size: A 4.3L V6 will get significantly better mileage than a larger V8 (like the 5.0L, 5.7L, or 7.4L options).
* Transmission: Automatic transmissions generally get slightly lower mileage than manuals.
* Driving conditions: City driving will yield lower MPG than highway driving. Terrain also plays a role.
* Vehicle condition: Proper maintenance (tune-ups, tire pressure) significantly impacts fuel economy.
* Payload and Towing: Hauling heavy loads drastically reduces gas mileage.
Therefore, there's no single answer. However, you can expect a range:
* 4.3L V6: Possibly 15-20 MPG combined (city and highway). Highway driving might see the higher end of this range.
* Larger V8s: Likely 10-15 MPG combined, potentially less depending on the factors listed above.
To get a more precise estimate, you'd need to specify the engine size and transmission type. You can also consult the owner's manual (if you have it), or search online for fuel economy data specifically for the exact model and engine of your 1996 Silverado. Sites like fueleconomy.gov (though it might not have data that far back in detail) or various car forums might offer some user-reported MPG figures.
