The 2011 Honda Odyssey has a fuel tank capacity of 19.5 gallons (about 74 liters).
This article explains the official specification, what it means for driving range, and practical tips for planning refuels on this popular family minivan.
Official tank size
The 2011 Odyssey is equipped with a 19.5-gallon (74-liter) fuel tank. Honda’s technical specifications and the model-year owner’s manual list this capacity as the standard tank size across all trims for that year.
Note that the capacity figure refers to the nominal tank size. The usable fuel before refueling can be slightly less due to reserve design and how the fuel gauge operates in practice.
- Capacity: 19.5 gallons (74 liters)
- Usable fuel vs. total capacity: reserve fuel means you may not reach the full 19.5 gallons before needing to refuel
- Fuel gauge behavior: designed to warn you before reaching empty, with a small reserve kept in the tank
Understanding these figures helps drivers plan trips and daily use, taking into account typical driving conditions and personal fuel economy.
Impact on range and planning
To estimate driving range, multiply the tank capacity by your real-world miles-per-gallon (mpg). Real-world fuel economy for the 2011 Odyssey varies with driving conditions, load, and climate, so actual ranges can differ widely between city and highway driving. Plan refueling before long trips and keep an eye on the gauge to avoid running low in unfamiliar areas.
Summary
The 2011 Honda Odyssey features a 19.5-gallon (74-liter) fuel tank. This nominal capacity, together with how the vehicle performs in real-world driving, determines how far you can travel between fill-ups. For trip planning, consider typical city versus highway use and err on the side of refueling sooner rather than later.
