The typical fuel tank capacity for most Honda Odysseys built in the last decade is 19.5 gallons (about 73.9 liters). Exact capacity can vary by model year and trim, so checking the owner's manual or the label on the fuel door provides the precise figure for a specific vehicle.
Below is a concise breakdown of how tank size has varied across major Odyssey generations and what drivers should expect when refueling.
Current generation (2011–present)
Before the list, note that this section covers the widely used capacity for modern Odysseys, which remains consistent across most trims.
- 2011–present Honda Odyssey: 19.5 gallons (73.9 L).
In everyday use, a full tank yields a practical driving range that depends on your mpg, driving conditions, and trim level, but 19.5 gallons is the standard reference for recent models.
Older generations
Older Honda Odyssey models generally used larger tanks, with capacities that varied by year and market. The sizes tended to fall in the low- to mid-20s gallons range, rather than the 19.5 gallons common in newer models.
- Pre-2011 Odysseys: capacities typically around the low- to mid-20s gallons, depending on year and trim.
For precise figures on a specific older model, consult the official specifications from Honda for that year or inspect the vehicle’s fuel-filler door label.
Summary
For most recent Honda Odysseys, the fuel tank capacity is 19.5 gallons. Older generations may have larger tanks, but the exact figure depends on the exact model year and trim. Always verify with the vehicle’s documentation or door-label specifications for an exact number.
