Why does the 7th-generation Accord have high fuel consumption?
2 Answers
The reasons for high car fuel consumption include abnormal tire pressure or switching to larger-sized tires; not turning off the engine during prolonged idling or frequent ignition; aggressive acceleration and frequent braking while driving; driving at high speeds in low gears or low speeds in high gears; fully open windows in summer and using air conditioning during traffic jams; not planning the route properly, driving on congested roads, and frequent lane changes. The combined fuel consumption of the 7th-generation Accord ranges from 4.2-6.5L/100km. There are a total of 9 models of the 7th-generation Accord currently on sale. The Rui Cool Edition and Rui Leading Edition have a combined fuel consumption of 4.2L/100km. The Phantom Night Rui Smart Edition and Phantom Night Rui Premium Edition have a combined fuel consumption of 4.4L/100km. The Comfort Edition, Luxury Edition, and Premium Edition have a combined fuel consumption of 6L/100km. The Phantom Night Flagship Edition and Phantom Night Premium Edition have a combined fuel consumption of 6.5L/100km. The above figures are the NEDC combined fuel consumption, which is higher in real-world conditions, averaging around 7.6L. The above figures are the NEDC combined fuel consumption, measured under the NEDC test procedure. Real-world fuel consumption is higher than this value, averaging around 7.6L. Methods to reduce fuel consumption: Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not obvious, it indicates a large amount of carbon deposits in the engine. In this case, the car must be taken to a 4S shop for professional technicians to clean the carbon deposits in the engine. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas during driving, and the oxygen sensor should be replaced at this time. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If not replaced for a long time, they become dirty and send incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits. Check the electronic control unit: Although the engine's electronic control unit is highly reliable, in older vehicles, various faults may inevitably occur.
I also experienced high fuel consumption with my 7th-gen Accord. Common causes include driving habits like frequent hard acceleration and braking, as well as repeated stop-and-go in city traffic which drastically increases fuel usage. Another factor is poor maintenance - clogged air filters or worn spark plugs reduce engine combustion efficiency, naturally consuming more fuel. I suggest starting with simple checks: insufficient tire pressure affects fuel economy, so inflate to recommended levels promptly. If that doesn't help, check for excessive AC use - running AC at full blast in summer increases fuel consumption by about 10%. Regular minor maintenance like oil and filter changes can effectively control fuel consumption, preventing long-term budget strain from high fuel costs.
