Why is the fuel consumption of Civic getting higher and higher?
3 Answers
Honda Civic's high fuel consumption is due to excessive carbon deposits in the engine throttle, which leads to increased fuel consumption. Cleaning the throttle can not only solve the high fuel consumption issue but also enhance the engine's power. The following are specific details about the Honda Civic: 1. Exterior: The Dongfeng Honda Civic has a stylish and fashionable appearance with smooth body lines. The hatchback design has undergone significant changes compared to the older models. 2. Interior: The interior of the Dongfeng Honda Civic is finely crafted with a fashionable design, prominent layering, and rich functional configurations. However, the extensive use of hard plastics results in a less-than-ideal tactile feel. The seats offer good comfort. 3. Space: The space performance is commendable, with ample legroom in both front and rear seats. The front seats have generous headroom, while the rear seats are slightly cramped in terms of headroom. The central floor hump in the rear is not very noticeable, enhancing practicality. The storage compartments are quite functional, and the trunk space has improved compared to older models. 4. Handling: The Dongfeng Honda Civic offers smooth gear shifting with clear gear positions. However, some users have reported "short gear travel with friction noise." The suspension tuning is moderately firm, the steering wheel is quite responsive, and the clutch pedal travel has been shortened compared to older models.
My 8-year-old Civic suddenly started consuming 2 liters more fuel per 100km recently. After troubleshooting, we identified three main issues. Carbon buildup in the throttle body was reducing air intake efficiency - the mechanic said this is a common issue with older vehicles. The original spark plugs had run 60,000km without replacement, significantly decreasing ignition efficiency. The air filter was forgotten during last maintenance and was completely clogged with willow catkins and dust. We also had the repair shop check the tire pressure, finding all four wheels were 0.3bar underinflated. After this round of maintenance, fuel consumption has basically returned to the 7.5L/100km level. An old car is like a middle-aged person's body - regular 'blood vessel cleaning' is crucial.
Just noticed the Civic's display showing fuel consumption over 9L/100km, which startled me into checking the maintenance manual. The 4S technician explained that increased summer fuel consumption is actually common, and recommended focusing on checking the A/C system's high-pressure pipe for leaks, as insufficient refrigerant can cause the compressor to run continuously under high load. Additionally, I have a habit of idling with the A/C on for long naps in the car, with the trip computer showing single idle fuel consumption reaching 1.8L/h. The most surprising find was half a case of mineral water permanently stored in the trunk, equivalent to carrying an extra child's weight. After adjusting these habits, fuel consumption has stabilized at 8.3L/100km. I suggest you weigh the total weight of items carried in your car.
