Why is the Changan CS35's fuel consumption high?

[AxelFitz]

The reasons for the high fuel consumption of the Changan CS35 may be due to engine carbon deposits, spark plug failure, abnormal tire pressure, and other factors. Below is relevant information: Configuration: The body dimensions are 4160x1810x1635mm, with a wheelbase of 2560mm, positioned as a compact SUV. In terms of appearance, it adopts a new trapezoidal front air intake grille design, replacing the previous V-shaped chrome styling seen on the concept car, while the fog lights retain the traditional circular design. Performance: Equipped with a 1.6L new Blue-Core engine, a Japanese Aisin original imported Ss-II automatic transmission, delivering a maximum power of 92kW (125PS) and a peak torque of 160Nm.

My Changan CS35 has noticeably high fuel consumption, and from my driving experience, I think it might be due to my driving habits. I tend to accelerate and brake aggressively, especially in congested urban areas—stepping hard on the gas and then slamming the brakes, which burns fuel quickly. Short-distance driving is also a big issue; I often drive just a few kilometers before parking, and the engine barely warms up before shutting down, leading to inefficiency and wasted fuel. Excessive use of the air conditioning has an impact too—setting it to the lowest temperature in summer makes the fuel gauge drop rapidly because the compressor consumes engine power. I’ve checked, and my tire pressure isn’t low, which could otherwise increase resistance. Maybe I should adopt a gentler driving style and reduce AC usage, and try longer trips to let the engine warm up properly—fuel consumption might drop significantly. Also, as the car ages, it’s normal for fuel efficiency to gradually decline. Regularly checking maintenance records can also help prevent high fuel consumption.

I noticed that my CS35's fuel consumption has increased significantly, and I believe it's closely related to the maintenance condition. Last time, the maintenance was delayed, and the air filter was completely clogged, causing the engine to breathe poorly and burn more fuel with lower efficiency. The engine oil hadn't been changed for too long, leading to poor lubrication and the engine working harder, which increased fuel consumption. The spark plugs had been used for over three years, causing misfires and more fuel waste. If the oxygen sensor is faulty, it misjudges emissions, leading to an imbalanced fuel system and excessive fuel injection, causing a surge in fuel consumption. I checked the tire pressure, and it was a bit low, increasing rolling resistance and naturally raising fuel consumption. I recommend regular replacement of the three filters and spark plugs in future maintenance to avoid these issues and stabilize fuel consumption. I also checked the fuel injectors for carbon buildup and noticed slight improvement after cleaning. As a car ages, part wear is natural, but maintenance should not be neglected. Good habits can save both fuel and money.

My CS35 has high fuel consumption, and I think it's due to driving and usage issues. Driving too aggressively with frequent acceleration and braking consumes more fuel. Short-distance commuting without warming up the engine wastes fuel. Always running the AC at maximum cooling increases fuel consumption. Poor fuel quality was an issue, but changing gas stations helped. Tire pressure is normal, but high consumption may require maintenance checks. I recommend driving smoothly and taking longer trips to warm up the engine to reduce fuel consumption.

My Changan CS35's fuel consumption has suddenly increased, and I think it's related to the usage environment. In winter, the prolonged cold start warm-up time and idling state consume significantly more fuel. During the hot summer, frequent use of the air conditioning compressor greatly increases fuel consumption. Poor road conditions in the city, with many traffic lights and frequent stops and accelerations, lead to lower engine efficiency and higher fuel consumption. On the highway, however, the fuel consumption is normal and not high. After several years of driving, natural wear and tear can cause a slight increase in fuel consumption. It's recommended not to warm up the car for too long; start driving within 30 seconds. Setting the air conditioning to a moderate temperature can save some fuel, and choosing smooth routes to avoid congestion can help. In terms of maintenance, I've checked and everything seems fine, but the overall increase might be due to a combination of habits and environmental factors. Regular maintenance can help alleviate this.

My CS35's abnormally high fuel consumption may be caused by multiple factors working together. Driving habits like my frequent aggressive acceleration - after adjusting to smoother driving, the fuel consumption slightly decreased, indicating behavior is a factor. Maintenance issues such as a dirty air filter - after replacement, ignition and intake efficiency improved somewhat. Fuel system problems like clogged injectors or fuel pump leaks can waste fuel. A faulty oxygen sensor leads to inaccurate monitoring and excessive fuel injection. Environmental factors like strong headwinds increase resistance and fuel consumption. Low tire pressure is common, but my checks showed normal levels - perhaps other points accumulated. I recommend a comprehensive inspection including the electronic control unit and fuel lines, preferably at a professional shop for diagnosis and troubleshooting. Developing good car usage habits will naturally control fuel consumption - don't neglect small issues accumulating into big problems.
