How many miles can you get out of a 2004 Honda Odyssey?
Expect roughly 434 miles of combined driving on a full tank, about 369 miles in city conditions or 543 miles on highway trips, depending on the vehicle’s condition and driving style.
Understanding these figures helps you estimate how far you can travel between fill-ups and how to maximize that distance on a long trip.
Key specs that determine range
Fuel economy (EPA ratings)
The following EPA estimates apply to the 2004 Odyssey with the 3.5L V6 and automatic transmission.
- City: 17 mpg
- Highway: 25 mpg
- Combined: 20 mpg
Note that real-world mileage can differ based on driving style and vehicle condition.
Fuel tank capacity
The Odyssey's fuel tank capacity is 21.7 gallons, which sets the upper bound for range when combined with the mpg figures above.
- Fuel tank capacity: 21.7 gallons
Using these numbers yields approximate ranges: city about 369 miles, highway about 543 miles, combined about 434 miles on a full tank.
How you can influence real-world range
Several factors can push the actual miles per tank above or below the EPA estimates.
- Vehicle age and maintenance: aging components such as oxygen sensors and the air filter affect efficiency.
- Weight and aerodynamics: cargo, roof racks, and towing can significantly reduce mpg.
- Driving style and conditions: aggressive acceleration, high speeds, and hilly terrain lower range; steady speeds and cruise control help.
- Tire condition and pressure: under-inflated tires increase rolling resistance and reduce mpg.
- Climate control usage: air conditioning and heating increase fuel use, especially at highway speeds.
In practice, you can expect the range to vary widely depending on these factors.
Tips to maximize miles per tank
Implement these practices to stretch your range on a 2004 Odyssey:
- Keep tires inflated to the factory-recommended pressure.
- Remove unnecessary cargo and roof racks when not needed.
- Drive smoothly: gradual acceleration, steady speeds, and early shifting.
- Use cruise control on highways to maintain a steady speed.
- Schedule regular maintenance: timely oil changes, air filter replacement, and spark plug checks.
- Avoid idling for long periods; turn off the engine if stopped for extended times.
- Plan efficient routes and avoid detours during peak traffic when possible.
While these tips help, the underlying numbers assume a healthy, well-maintained vehicle and typical driving conditions.
Bottom line
For planning purposes, a full tank in a 2004 Honda Odyssey yields roughly 434 miles of combined driving, around 369 miles in city conditions, or about 543 miles on long highway trips, based on EPA estimates and a 21.7-gallon tank. Real-world results will vary based on age, maintenance, cargo, and driving habits.
Summary
The 2004 Honda Odyssey offers a practical range primarily influenced by its EPA-rated efficiency and its fuel-tank size. By understanding the numbers and following some best practices, drivers can maximize how far they can travel between fill-ups.

How many miles is too much for a Honda Odyssey?
There is no single mileage that is "too much" for a Honda Odyssey, as a well-maintained one can last well over 200,000 miles. Instead of just focusing on the number, consider a vehicle's maintenance history and overall condition, as a high-mileage van with a good record is often a better purchase than a low-mileage one with poor upkeep. Look for a history of regular service, especially for major components like the timing belt and transmission, as these are critical for longevity.
Factors to consider
- Maintenance history is key: A vehicle with extensive and regular maintenance will be more reliable than one that has been neglected, regardless of the mileage.
- Preventative maintenance: Be especially aware of a vehicle's timing belt and transmission maintenance.
- Timing belt: This is a critical and costly job, often due around 100,000-105,000 miles or every seven years. If the service records are missing, assume it needs to be done immediately.
- Transmission fluid: Regular transmission fluid changes are vital. If the service history is unknown, consider a fluid flush as a precaution.
- Over 200,000 miles: While many Odysseys can exceed 200,000 miles, it is more likely to require significant and costly repairs at this point, according to this Reddit thread. A professional inspection is highly recommended for any vehicle with this much mileage.
- Overall condition: Look for other signs of wear, such as issues with suspension bushings, engine mounts, and general wear and tear on the body and interior, suggests this Reddit thread.
What to do if you're considering a high-mileage Odyssey
- Get a professional inspection: Have a trusted mechanic inspect the vehicle thoroughly before you buy it.
- Check service records: Ask for all maintenance records to verify when major services, such as the timing belt, were performed.
- Negotiate based on needed repairs: Be prepared to account for the cost of any immediate maintenance or repairs required, especially if the timing belt or other major service is due soon.
How many miles can a 2004 Odyssey last?
On average, a well-maintained Honda Odyssey can last for 200,000 miles or more. Some Odyssey owners have reported achieving even higher mileage, with their vehicles still running smoothly. However, this is not a guarantee for every vehicle, as individual experiences may vary.
Can a Honda last 400,000 miles?
The Lifespan of a Honda Civic
That's not an exaggeration. Many civic owners have reported hitting high numbers on their odometer, sometimes reaching 400,000 miles with regular maintenance. It's common to find used Honda Civics on the market with well over 150,000 miles on them and still running strong.
