How big is the fuel tank on a 2025 Honda Odyssey?
The 2025 Honda Odyssey uses a 19.5-gallon (about 74-liter) fuel tank.
That capacity influences how far you can travel between fills, your refueling routines, and overall trip planning. Honda keeps the tank size consistent across trims for the 2025 model year, pairing it with a 3.5-liter V6 and a 10-speed automatic transmission aimed at balancing power with efficiency.
Official specifications
A quick snapshot of the fuel-tank details for the 2025 Odyssey:
- Fuel tank capacity: 19.5 gallons (74 liters)
- Estimated driving range: approximately 420–430 miles (about 675–690 kilometers) on a full tank at typical EPA-estimated fuel economy
- Fuel economy: EPA estimates around the low-to-mid 20s mpg combined, with actual range varying by driving conditions
Note that real-world range can vary based on driving habits, payload, terrain, and climate control use.
Why the tank size matters for owners
The 19.5-gallon capacity provides a practical balance for a family minivan, minimizing frequent visits to the gas station on long trips while keeping overall vehicle weight and cost reasonable. Drivers who consistently haul passengers or cargo may see shorter range than those who drive mainly on highways without heavy loads.
Summary
The 2025 Honda Odyssey is equipped with a 19.5-gallon (74-liter) fuel tank, supporting an estimated range of roughly 420–430 miles on a full tank under typical conditions. Real-world range will vary with driving style, terrain, and weather, but the capacity stays consistent across trims for the model year.
