* Check the sticker inside the driver's side doorjamb: This sticker often contains the original EPA fuel economy estimates.
* Consult the owner's manual: The owner's manual will also list the expected fuel economy.
* Look up the specifications online: Websites like Edmunds, Kelley Blue Book, or FuelEconomy.gov might have information based on the engine type (e.g., 2.5L, 3.1L V6, etc.) and transmission (automatic or manual). You'll need to know your car's specific engine and transmission to find the most accurate data.
Keep in mind that actual gas mileage can vary based on driving habits, vehicle condition, and road conditions. The EPA estimates are just averages.
