In practical terms, an 18.5-gallon tank typically yields a driving range that varies with engine choice, driving conditions, and efficiency, but it generally supports a substantial number of miles between fill-ups. Always check the door jamb label or owner's manual for the exact specification for your car, especially if you own a special edition or a region-specific variant.
Notes on older and classic Impalas
Across earlier generations, tank sizes varied more widely due to changes in body style, engine options, and market specifications. Because the Impala has been produced in many configurations since the 1950s, the exact capacity is year- and model-specific. If you own a classic or a less common variant, consult the vehicle’s data plate or a year-specific reference to confirm the precise capacity.
How to verify fuel tank size for your Impala
The most reliable sources are the vehicle’s data label on the door, the owner's manual, or Chevrolet’s official documentation for your year and trim. If those are unavailable, you can search for your exact year, model, and VIN on Chevrolet’s site or trusted automotive databases to confirm the tank size.
Summary
For most modern Chevy Impalas, plan on an 18.5-gallon fuel tank, with some variation by year and trim. If you’re shopping for a specific year or a classic model, verify the exact figure on the data label or in the year-specific manuals, since capacities can differ across generations.
