Why is the Changan CS35's fuel consumption high?
3 Answers
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.
