How many miles does a 2003 Chevrolet Impala LS have to the gallon?

The fuel economy of a 2003 Chevrolet Impala LS varies depending on the engine (3.4L V6 or 3.8L V6) and driving conditions (city vs. highway). You won't find a single definitive answer.

However, you can expect EPA estimates to be in the range of:

* City: 17-20 mpg

* Highway: 25-28 mpg

These are estimates, and actual mileage will likely be lower depending on driving habits, vehicle condition, and other factors. To find the *actual* MPG for a specific car, you'd need to look at its individual history (if available) or test it yourself.
