* Driving conditions: City driving will result in significantly lower fuel economy than highway driving. Stop-and-go traffic, idling, and aggressive acceleration all reduce MPG.
* Vehicle condition: Proper maintenance (tire pressure, tune-up, etc.) significantly impacts fuel efficiency. A poorly maintained truck will consume more fuel.
* Payload and towing: Hauling heavy loads or towing a trailer dramatically reduces fuel economy.
* Tire size: Larger tires can affect fuel economy.
Therefore, providing a single MPG figure is misleading. However, you can expect fuel economy in the range of 13-17 MPG combined (city and highway). You might see slightly higher MPG on the highway and significantly lower in city driving.
To find a more precise estimate for *your* specific truck, consider consulting the original owner's manual (if you have it) or checking online resources dedicated to fuel economy data, though data for older vehicles can be limited.
