* Engine size: Different engine options were available for the 1997 Fiesta, and each will have a different fuel consumption rate.
* Driving style: Aggressive acceleration and high speeds dramatically reduce fuel economy.
* Vehicle condition: A well-maintained vehicle will generally get better gas mileage than one that's neglected.
* Terrain: Driving in hilly or mountainous areas will use more fuel than driving on flat roads.
* Tire pressure: Properly inflated tires improve fuel efficiency.
Therefore, it's impossible to give a precise mileage figure for a full tank. To find an estimate, you should:
1. Check your owner's manual: It will likely list the EPA estimated fuel economy (miles per gallon or mpg) for your specific Fiesta engine.
2. Look up fuel economy data online: Websites like fueleconomy.gov (if you're in the US) or similar sites for your country might have data on 1997 Ford Fiestas. Search for "1997 Ford Fiesta fuel economy."
3. Calculate it yourself: Fill your tank completely, reset your trip odometer, and drive until the tank is nearly empty. Divide the miles driven by the number of gallons it took to refill the tank to get your mpg. Then multiply that by your tank's capacity (in gallons) to get your approximate range.
Keep in mind that any figure you find will be an *estimate*. Your actual mileage may vary.
