22 MPG combined is the headline for the 2023 Honda Odyssey 3.5L 6-cyl. Let’s be clear: No one buys an Odyssey expecting Prius-like efficiency. They buy it for its cavernous interior, its supremely comfortable ride, and its unmatched practicality for hauling kids and their associated gear. This isn’t a vehicle purchased for hypermiling; it’s a rolling family room, and its fuel economy needs to be understood in that context.

City and highway performance

The EPA estimates the 2023 Honda Odyssey will achieve 19 MPG in the city and 28 MPG on the highway. This split reflects the Odyssey’s purpose. A good portion of its life will likely be spent navigating stop-and-go traffic, school zones, and errand runs. The highway figure, while not stellar, is respectable enough for long road trips where comfort and space are far more critical than saving a few dollars on the fuel bill. Realistically, the Odyssey’s 3.5L V6 needs to work to move its considerable weight, no matter the environment.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,000 for the 2023 Honda Odyssey. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that fuel prices fluctuate, and your individual driving habits may significantly alter this number. Someone doing mostly short trips in congested areas will likely exceed $2,000, while someone clocking mostly highway miles could potentially spend less. It’s best to use this as a reasonable benchmark, understanding that your personal experience will vary.

Real-world expectations

While the EPA provides a standardized testing methodology, “your mileage may vary” is more than just a catchy phrase. Real-world fuel economy depends heavily on driving style, terrain, weather conditions, and even tire pressure. Expect the Odyssey to deliver somewhere in the high teens to low twenties in mixed driving. Consistent highway cruising should get you closer to that 28 MPG rating, but aggressive acceleration or frequent short trips will pull the average down. Payload also matters; a fully loaded Odyssey will consume more fuel than one carrying only the driver. For all Honda fuel economy data, you can check out our Honda make page.

How it compares

The minivan segment is a competitive one, and fuel economy is an important consideration for many buyers. The Chrysler Pacifica, with its available plug-in hybrid powertrain, offers a significant advantage in city driving, potentially achieving much higher overall MPG if driven mostly on electric power. However, a non-hybrid Pacifica achieves about 19/28/22 MPG (city/highway/combined), making it essentially a wash with the Odyssey in normal conditions. The Toyota Sienna exclusively uses a hybrid powertrain, delivering a significantly better 36 MPG combined. However, some buyers prioritize the Odyssey’s more traditional driving feel over the hybrid experience. The Kia Carnival, with its V6, nets 19/26/22, showing just how competitive all the minivans are in this segment. When assessing ODYSSEY MPG across all years,

Tips to maximize efficiency

Smooth and steady acceleration is key to good fuel economy. Avoid aggressive starts and hard braking, anticipating traffic flow to maintain momentum. The Odyssey’s 10-speed automatic transmission is designed to keep the engine in its optimal efficiency range, but it can only do its job if you drive predictably.

Regular maintenance is critical. Ensure your tires are properly inflated; low tire pressure increases rolling resistance and reduces fuel economy. Keep up with scheduled oil changes and air filter replacements, as these contribute to optimal engine performance. A well-maintained Odyssey is an efficient Odyssey.

Limit idling. Modern engines do not need extended warm-up periods. If you’re waiting for someone or stopped for more than a minute, turn off the engine. Excessive idling consumes fuel without covering any distance, significantly impacting city MPG.

Consider using the Odyssey’s “Econ” mode, if equipped. This mode adjusts throttle response and transmission shift points to prioritize fuel efficiency. While it may slightly reduce performance, it can improve MPG, especially in city driving. Experiment to see if the trade-off suits your driving style.

Plan your trips efficiently. Combine errands into a single outing to minimize cold starts, which are less fuel-efficient. Choose routes that avoid stop-and-go traffic whenever possible. A little planning can significantly reduce your overall fuel consumption.
