The 2019 Honda Odyssey’s fuel tank capacity is 19.5 gallons (73.9 liters).
This article explains the official tank size, how it translates to real-world driving range, and what owners should know about the tank across the 2019 Odyssey lineup.
Official tank size and measurements
The fuel tank used on the 2019 Odyssey is a single, uniform tank shared across trims, designed to balance capacity with the minivan’s weight and efficiency.
- Fuel tank capacity: 19.5 gallons (73.9 liters)
- Fuel economy (EPA combined): about 22 miles per gallon
- Estimated full-tank range: roughly 429 miles (690 kilometers) on a full tank at the EPA combined efficiency
Note that real-world range can vary with driving conditions, cargo, and climate control use, but the tank size itself is consistent across 2019 Odyssey models.
Estimated driving range and real-world factors
Understanding how the tank size translates into distance requires looking at MPG variations and practical factors that affect fuel use.
Key factors influencing range
Driving style, terrain, temperature, and how heavily the vehicle is loaded can all change how far you can travel on a full tank.
- EPA combined mpg for 2019 Odyssey: about 22 mpg
- Theoretical full-tank distance (based on 22 mpg): about 429 miles
- Real-world range typically varies by driving conditions and usage
In practice, you should expect some variation from the theoretical estimate, but the 19.5-gallon tank provides a solid, predictable refueling window for family trips and daily use.
Summary
The 2019 Honda Odyssey carries a 19.5-gallon (73.9-liter) fuel tank, enabling an estimated range of around 430 miles under typical combined MPG. Real-world range will vary with driving conditions, but the tank size remains a constant reference point for planning trips and fueling stops.
