How many gallons of gas does a Chevy SS hold?
The Chevy SS fuel tank holds about 18.5 gallons (70 liters) of gasoline.
The Chevy SS was a high-performance rear-wheel-drive sedan produced by Chevrolet from 2013 through 2017 in the United States, based on the Holden Commodore VF. Knowing the tank size helps drivers estimate range and refueling frequency in everyday use.
Tank size and practical range
Here are the official capacity figures, plus how they translate into potential driving distance under typical conditions.
- Fuel tank capacity: 18.5 gallons (70 liters).
- EPA fuel economy (approximate, 2014–2017): 16 mpg city / 23 mpg highway / 19 mpg combined.
- Estimated driving range on a full tank (varies with conditions): about 296 miles in city driving, about 426 miles on the highway, and about 351 miles combined using the combined mpg figure.
Before listing the data, note that the numbers below reflect the model’s standard tank size and typical EPA ratings for range estimates.
In practical terms, a Chevy SS with a full tank can cover several hundred miles depending on driving style and conditions.
Model year consistency
The fuel tank capacity remained 18.5 gallons across all Chevrolet SS models built from 2013 to 2017, with no changes in tank size during its production run.
Summary
Final takeaway: The Chevy SS holds 18.5 gallons (70 liters) of gasoline in its tank. With EPA ratings around 16/23/19 mpg, expect roughly 296 miles of city driving, 426 miles on highways, and about 351 miles combined on a full tank. The capacity was constant throughout the 2013–2017 model years.
Is the Chevy SS good on gas?
It's not very fuel efficient. On our 637-mile stint in the SS we averaged 21 mpg overall, with the vast majority of those miles between 70 and 80 mph on the highway. A Corvette that we drove down with averaged 29 mpg during the highway stretches, proving General Motors Company (NYSE:GM) engineers can do better.
Is 16 gallons of gas a full tank?
Most standard passenger cars hold between 12 to 16 gallons of gas. However, this can vary based on the size and type of the vehicle. Compact cars might have smaller tanks, while full-sized sedans could offer a larger capacity.
How big is the gas tank on a Chevy SS?
The gas tank size for a Chevy SS depends on the model year and specific vehicle. The Australian-built Chevrolet SS sedan, produced from 2014-2017, has a fuel capacity of 18.8 gallons. For a Chevrolet Camaro SS, the tank is 19 gallons.
- Chevrolet SS (2014-2017 sedan): 18.8 gallons
- Chevrolet Camaro SS: 19 gallons
Why are Chevy SS so rare?
Chevy SS sedans are rare because they were only produced for a short four-year run (2014–2017) with low production numbers, partly due to a lack of marketing and poor sales figures that were only about 3,000 per year. The car was imported from Australia as a Holden Commodore and its production was ultimately limited by the closure of the Holden plant, according to Quora.

- Limited production: The car was only produced for four model years, ending after 2017, which inherently limits the total number of vehicles available.
- Low sales and poor marketing: Despite being a high-performance sedan with a V8 engine, sales were lackluster, partly because Chevrolet did not heavily market the car.
- Imported from Australia: The Chevy SS was an imported Holden Commodore, and its production run was tied to the Australian Holden plant, which GM later shuttered.
- Short lifespan: The vehicle was essentially a stop-gap model to honor a prior deal to import sedans from Holden after the Pontiac G8 was canceled, and there was no plan for a long-term replacement.
