* Engine size: The Silverado came with a wide range of engine options in 1994, from small inline-6s to large V8s. A smaller engine will get significantly better gas mileage than a larger one.
* Transmission: Automatic or manual transmissions will affect fuel economy.
* Vehicle condition: Proper maintenance (tuned engine, properly inflated tires, etc.) significantly impacts fuel economy.
* Driving habits: Aggressive driving (rapid acceleration and braking) reduces fuel efficiency.
* Payload and towing: Hauling heavy loads or towing a trailer will drastically reduce gas mileage.
Therefore, it's impossible to give a single, accurate estimate. However, you can expect a range like this:
* Best-case scenario (small engine, manual transmission, light load, careful driving): Possibly in the high teens (mpg) or low 20s (mpg). This is optimistic.
* Worst-case scenario (large engine, automatic transmission, heavy load, aggressive driving): Possibly in the low teens (mpg) or even single digits (mpg). This is also possible.
* Average expectation (depending on engine size and driving style): Likely somewhere in the 12-18 mpg range for most everyday driving situations.
To get a more precise estimate, you need to know the specific engine and transmission of the truck. You can find that information on the vehicle's VIN sticker or documentation.
