The 2005 Honda Civic typically comes with a 13.2-gallon (about 50 liters) fuel tank. This size is standard for North American models and is the same across sedan and coupe bodies and across the common trims for that year.
In this article, we break down the official capacity, what it means for driving range, and note any regional variations you might encounter when comparing different markets or configurations of the 2005 Civic.
Official tank capacity for the 2005 Civic
Before listing the figure, note that Honda published a single standard tank size for most 2005 Civics used by buyers in the United States and Canada. The figure below reflects the common specification for these markets.
- 2005 Honda Civic (US/Canada): fuel tank capacity of 13.2 U.S. gallons (50 liters). This applies to the common sedan and coupe body styles and to DX/LX/EX trims in these markets.
In practice, this tank size supports a practical driving range of roughly 370–420 miles (about 600–680 kilometers) between fills under typical mixed driving, depending on engine type and driving conditions.
What the tank size means for range
Fuel tank capacity is one factor in how far you can drive on a tank. The Civic’s fuel efficiency varies by engine, transmission, and driving style, but the 13.2-gallon tank accommodates a broad range of driving distances before a refill is needed.
Estimating driving range
Using a rough combined-efficiency figure from the era—about 28–32 miles per gallon (mpg)—the expected range is approximately 370–420 miles per full tank. In kilometers, that’s roughly 600–680 km.
Variations by market
While 13.2 gallons (50 liters) is the commonly cited capacity for North American Civics, some regional specifications or rounding in manuals can show slight differences. The official specification for the 2005 Civic in major markets generally centers around 50 liters.
Summary
The 2005 Honda Civic typically comes with a 13.2-gallon (50-liter) gas tank. This size is consistent across sedan and coupe models in North America, providing a practical range of roughly 370–420 miles between fills under typical driving. Range will vary with engine choice and driving habits.
