10-year-old Odyssey's actual fuel consumption is around 10 liters per 100 kilometers. Here is additional information: 1. Introduction: The Odyssey is a vehicle launched by , which went on sale nationwide in January 2007. It is equipped with a satellite navigation system, featuring an 8-inch large display screen and voice guidance function, and uses a 2.4L i-VTEC high-performance engine with variable valve timing and lift. 2. Manufacturer: Honda is the world's largest motorcycle manufacturer, and its automobile production and scale also rank among the top ten in the world. Founded in 1948 by the legendary figure Soichiro Honda, the company is headquartered in Tokyo with approximately 110,000 employees. Honda has become a multinational automobile and motorcycle production and sales group. In addition to automobiles and motorcycles, its products also include power machinery such as generators and agricultural machinery.

















I've been using my 10-year-old Odyssey for almost five years now. During rush hour commutes in the city, it basically consumes around 13 to 14 liters per 100 kilometers, and it's even more fuel-hungry with the AC on full blast. It's a bit more economical on highways, roughly 9 to 10 liters, but the wind noise is noticeably louder. That's the trouble with older cars—their fuel consumption is much higher than new ones. A friend's 2018 Odyssey manages around 11 liters. Actually, replacing the air filter, cleaning carbon deposits, and using full synthetic oil can slightly reduce fuel consumption, but the key is driving habits—avoid stomping on the gas and hard braking. My car averages about 12 liters per 100 kilometers overall. When the fuel light comes on, I usually fill up with 300 yuan worth, which gets me around 400 kilometers. If an older car is well-maintained, its fuel consumption is still somewhat acceptable.

The actual fuel consumption of a 10-year-old Odyssey varies quite a bit. For example, during daily city commuting in traffic jams, it typically fluctuates between 13 to 15 liters per 100 kilometers; in suburban areas with smoother driving, it can drop to around 11 liters. On the highway at a steady speed, it can be reduced to about 9 liters. I've noticed several key factors affecting this: first, maintaining stable tire pressure is crucial—insufficient pressure can increase fuel consumption by 5%; second, regularly clearing out trunk clutter, as excessive weight makes the car heavier; third, cleaning the throttle body every 30,000 kilometers, as excessive carbon buildup can increase fuel consumption. If the car sits unused for long periods, the fuel lines may clog, making it harder to start and wasting fuel. Using fuel additives can help alleviate some issues in older cars. Overall, consumption is generally above 12 liters, and the GL8 from the same era consumes about half a liter more than the Odyssey.

I previously helped a friend test his 2010 Odyssey, and the actual combined fuel consumption in urban areas was around 12-13 liters. The main reason for this is the wear and tear on the 2.4L engine over time, along with clogged fuel injectors and aged spark plugs, which reduce combustion efficiency. Additionally, the transmission in older cars shifts more slowly, often staying in lower gears at higher RPMs, naturally consuming more fuel. I recommend checking three areas: first, the oxygen sensor—even if the check engine light isn’t on, it might still be inaccurate; second, the carbon canister purge valve—leaking fuel vapor also wastes gas; and finally, the coolant temperature sensor—the ECU defaults to injecting more fuel when the coolant temperature is low. If this car is often fully loaded or used for short trips, it could even reach 14 liters per 100 km.

I drove a 2010 Odyssey for two years myself. A full tank would last about 450 kilometers, averaging 11 to 12 liters per 100 kilometers. The key factor is road conditions – on routes with many traffic lights, start-stop fuel consumption can account for up to 30%. Don't use oil that's too viscous; 5W-30 is just right. Running the air conditioning at maximum can increase fuel consumption by about 15%, which is especially noticeable in summer. Another important thing: the brake calipers are prone to sticking. Driving with the brakes engaged is not only dangerous but also burns extra fuel. If the engine mounts are worn out, the vibration increases, and the ECU may misjudge power demand, leading to extra fuel injection. Regularly changing the transmission fluid can save about half a liter of fuel. After all, older cars always have their quirks.

The actual urban fuel consumption of that generation Odyssey generally fluctuates around 12L. I've interacted with many owners of the same model - those who drive more on highways can reduce it to 9L, but none doing city commutes get below 11L. For older cars to control fuel consumption, regular is key: change the air filter every six months to ensure air intake; using double iridium spark plugs can improve ignition efficiency; switching to low rolling resistance tires can save 3% fuel. Is opening windows more fuel-efficient than using AC in summer? Wrong! Above 60 km/h, open windows create more wind resistance. Keeping folding chairs in the trunk is better than leaving a toolbox there. Also, 92 and 95 octane gasoline make no difference in fuel consumption for older cars, but fuel system cleaner should be added monthly. The average fuel consumption for this car is about 12L - it's hard to reduce unless you overhaul the engine.
