How big is a 2011 Malibu gas tank?
The 2011 Chevrolet Malibu's fuel tank capacity is 18 gallons (about 68 liters).
This figure represents the standard nominal capacity listed for the model year and typically applies across the main gasoline engines offered that year. Driving range will vary with engine choice and driving conditions, but the tank size itself remains constant.
Tank size across the 2011 Malibu lineup
Chevrolet's official specifications for the 2011 Malibu show a single fuel tank capacity of 18 gallons (68 liters). This capacity is used for the primary gasoline engines available that year, including the 2.4-liter four-cylinder and the 3.6-liter V6. There were no factory options to alter the tank size for standard U.S. models in that year.
What affects how far you can go on a full tank?
Even with a fixed 18-gallon tank, your driving range depends on real-world fuel economy, which varies with driving style, city versus highway conditions, temperature, and load. A more fuel-efficient Malibu will travel further on a full tank than a less efficient one, though both share the same nominal tank size.
Why the tank size matters for owners
Knowing the 18-gallon capacity helps with planning fuel stops, maintenance intervals, and trip budgeting. For long road trips or frequent highway driving, this standard size provides a reliable baseline for estimating range and fuel costs.
Summary
The 2011 Malibu uses an 18-gallon (approximately 68 liters) fuel tank across its main gasoline configurations. This consistent tank size serves as a practical reference for planning fuel stops and estimating range, with actual distance per tank determined by mpg in real-world driving.
