* Driving conditions: City driving will yield significantly lower MPG than highway driving. Topography (hills, mountains) also greatly impacts fuel economy.
* Vehicle condition: Proper maintenance (tune-up, air filter, etc.) is crucial for optimal fuel efficiency. A poorly maintained engine will use more fuel.
* Driving style: Aggressive acceleration and high speeds dramatically reduce fuel economy.
* Load: Hauling heavy loads will significantly lower MPG.
* Tire pressure: Properly inflated tires improve fuel efficiency.
Considering all these variables, it's difficult to give a precise MPG figure. However, you can expect somewhere in the range of 12-18 MPG under reasonably good conditions and with a well-maintained truck. Real-world experience suggests that 15 MPG is often cited as a reasonable average, but it could easily be lower or higher depending on the factors above. You'll likely see lower MPG in city driving and higher on the highway.
