How big is a 2012 Chevy Impala fuel tank?
The 2012 Chevy Impala uses an 18.5-gallon (about 70-liter) fuel tank.
For context, this capacity is standard across the 2012 Impala lineup, including LS, LT and LTZ models, and applies to the gasoline engines offered that year. The tank size influences driving range, fuel stops and planning for longer trips.
Tank capacity overview
The Impala's fuel tank is designed to balance trunk space and overall driving range. A larger tank helps reduce refueling frequency on long highway drives, while a smaller tank can have benefits for weight distribution and efficiency in some driving scenarios. In the 2012 model year, Chevrolet used a single standard capacity across trims.
Key facts about the 2012 Impala fuel tank:
- Capacity: 18.5 gallons (70 liters).
- Uniform across trims (LS, LT, LTZ) and engine options for that year.
- Located in the rear of the vehicle, integrated with the trunk area, and designed for standard gasoline fuel.
Knowing the tank size helps with estimating your driving range and planning fuel stops on trips.
Driving range and fuel economy considerations
Fuel range depends on the engine, transmission, driving conditions and your driving style. The 2012 Impala offered two gasoline engines; depending on which you have and how you drive, the miles you can travel on a full tank will vary. To estimate range, multiply the tank capacity by the vehicle’s miles-per-gallon (mpg) rating for your engine and driving conditions.
Estimating range formula
Range (miles) ≈ Tank capacity (gallons) × MPG (miles per gallon) for your typical driving mix. Use the EPA window sticker or your on-board computer to get your actual mpg, then apply the formula.
In practice, many drivers see ranges in the hundreds of miles per tank, with highway driving yielding better efficiency than city driving.
Summary
The 2012 Chevy Impala carries an 18.5-gallon fuel tank, about 70 liters, a size that supports long drives between refueling. Across the LS, LT and LTZ trims, and with the available gasoline engines that year, capacity remained constant, making fuel planning straightforward for owners and buyers of that model year.
