* Driving conditions: City driving will yield considerably lower MPG than highway driving. Aggressive acceleration and idling will also reduce fuel economy.
* Vehicle condition: Properly maintained vehicles (tuned engine, properly inflated tires, etc.) will get better mileage than neglected ones.
* Payload and towing: Hauling heavy loads or towing a trailer dramatically reduces fuel economy.
* Transmission type: Automatic transmissions generally get slightly lower mileage than manuals (though this engine was almost exclusively automatic in this model year).
Considering all these variables, you can expect a range of 10-15 MPG combined (city and highway driving). Highway driving might push towards the higher end of that range (possibly even a little over), while city driving might drop below 10 MPG.
It's important to remember that these are just estimates. Your actual mileage may vary. Checking your owner's manual might provide a factory estimate, though keep in mind that real-world results often differ.
