* City driving: Around 20-22 mpg
* Highway driving: Around 28-30 mpg
These are estimates, and your actual mileage will depend on driving habits, vehicle condition, and other factors. Checking the official EPA fuel economy estimates for the specific trim level of the 2007 Cavalier would give you the most accurate information. You can usually find this information on the EPA's website (fueleconomy.gov) or in the owner's manual.
