How many miles does a Chevy Impala get on a full tank of gas?
The short answer is that most Impalas cover about 400 to 500 miles per tank under typical mixed driving, with real-world results varying by year, engine and driving habits.
What affects fuel range?
Range depends on the size of the fuel tank, the engine’s efficiency, and how you drive. Heavier engines and more city driving tend to reduce mileage, while steady highway cruising can improve it. Over the years, Impala tank sizes and EPA fuel-economy ratings have shifted with different generations, so the exact distance per tank isn’t identical across models.
Estimated ranges for common configurations
Presented below are rough figures for typical Impala configurations to give you a sense of scale. Actual numbers may vary by model and condition.
- Modern Impalas (roughly 2014–2020): about an 18.5-gallon tank with real-world mpg commonly in the low-to-mid 20s combined. Expected range roughly 400–470 miles per fill.
- Earlier models (late 1990s–2013): similar tank size with varying efficiency; expect about 380–450 miles under typical mixed driving.
- Classic era Impalas (pre-1986): many used larger tanks and different engines, leading to a broad range of hundreds to potentially 600+ miles per tank depending on configuration and driving style.
Note: These are rough ranges. For your specific car, check the owner’s manual or the EPA label in the door jamb or fuel cap to confirm tank capacity and mpg, then multiply by the tank size to estimate range accurately.
How to estimate your own range
To estimate the distance you can travel on a full tank, use these steps:
- Find your car’s fuel tank capacity (in gallons). This is listed in the owner's manual or on the vehicle’s door jamb label.
- Check your real-world miles-per-gallon (MPG) from recent trips, or use the EPA combined MPG for your model as a starting point.
- Multiply the tank capacity by your MPG: Estimated range = gallons × MPG.
- Factor in driving conditions: city trips, hills, or aggressive driving will reduce range; steady highway speeds typically yield higher range.
In practice, you’ll get a practical sense of range after a few full-tank fills, and you can adjust expectations accordingly.
Summary
Across model years, the Impala typically delivers in the neighborhood of 400 to 470 miles per full tank in mixed driving, with older or high-performance configurations capable of more or less depending on tank size and efficiency. For a precise figure, use your car’s official tank capacity and real-world MPG to calculate the expected range.
