How many miles can you get per gallon on a Chevy cavalier?

The fuel economy of a Chevy Cavalier varies significantly depending on the model year, engine size, and driving conditions. There's no single answer.

However, you can generally expect somewhere in the range of 20 to 30 miles per gallon (mpg), combined city and highway driving. Older models might be on the lower end of that range, while more recent (for a Cavalier, this means late 90s to early 2000s) models with smaller engines might achieve the higher end.

To find a more precise estimate, you'll need to specify the exact year and engine of the Cavalier in question. You can then consult the owner's manual or online resources like the EPA's FuelEconomy.gov website.
