You'll find a range of EPA estimates, typically between 15 and 25 MPG combined (city and highway). A smaller engine and manual transmission generally yields better fuel economy than a larger engine and automatic transmission. Actual mileage will likely be lower than the EPA estimates, depending on your driving habits.
To find a more precise estimate for *your specific* 1998 Ford Ranger, you should:
* Check the sticker in the driver's side doorjamb: This often lists the original fuel economy estimates.
* Consult the owner's manual: It will provide fuel economy information relevant to your truck's configuration.
* Use online resources: Websites like fueleconomy.gov (in the US) may provide data based on reported owner experiences, though the accuracy varies.
Keep in mind that age and condition of the vehicle also impact fuel economy. Poor maintenance can significantly reduce MPG.
