How much gas does a 2010 Chevy Cobalt hold?
The 2010 Chevy Cobalt can hold about 13.0 gallons (roughly 49 liters) of gasoline in its fuel tank.
In this article, we examine the tank size across the 2010 Cobalt lineup, what that means for driving range, and practical notes for planning refuels.
Tank size across the 2010 Cobalt lineup
For the 2010 model year, Chevrolet offered several engine options, including the 2.2-liter Ecotec and the 2.4-liter Ecotec. The official specification for all these variants lists a fuel tank capacity of 13.0 gallons (49 liters), meaning the tank size remained consistent regardless of engine choice or trim level in that year.
Estimated driving range on a full tank
Range depends on the chosen engine and driving conditions. With typical mixed driving, most Cobalts from this era achieve roughly 26–34 miles per gallon (mpg). On a full 13.0-gallon tank, that translates to an approximate range of about 325 to 450 miles (roughly 525 to 725 kilometers). Highway driving on the more efficient setups tends to be toward the upper end, while city driving lowers the figure.
Practical notes
Actual usable fuel is slightly less than the nominal capacity due to reserve and how the fuel gauge is calibrated. Variations can occur between individual vehicles due to manufacturing tolerances, fuel system wear, and driving style. It’s wise to refuel before the gauge approaches empty to avoid running out unexpectedly.
Summary
The 2010 Chevy Cobalt’s gas tank holds about 13 gallons (49 liters) of gasoline, a figure that applies across the year’s engine options. Depending on driving conditions, you can expect a practical range in the mid-300s to around 450 miles on a full tank. Use this baseline for trip planning and monitoring fuel economy over time.
