* Driving habits: Aggressive acceleration and braking, excessive idling, and high speeds will significantly reduce fuel economy.
* Vehicle condition: Proper maintenance (including tune-ups, tire inflation, and a clean air filter) is crucial for optimal fuel efficiency.
* Terrain: Driving in hilly or mountainous areas will reduce fuel economy compared to flat terrain.
* Climate: Cold weather can slightly reduce fuel efficiency.
You'll likely find that highway mileage is higher than city mileage. To get a more precise estimate for a specific car, you might look at owner reviews or forums dedicated to that model year. The EPA's fuel economy estimates from that time may also provide a general range, but remember they are based on testing conditions and may not reflect real-world driving.
