What are the reasons for the high fuel consumption of Changan CS35?
2 Answers
The reasons for the high fuel consumption of Changan CS35 are as follows: Engine carbon deposits: When the engine has carbon deposits and is not cleaned in time, the car's fuel consumption will increase. Spark plug failure: When the spark plug fails, the car's acceleration will slow down, thereby increasing fuel consumption. Abnormal tire pressure: When the tire pressure is abnormal, the impact on fuel consumption is immediate, as increased friction leads to higher fuel consumption. Poor fuel injector atomization: Poor fuel injector atomization can cause blockages, thereby increasing fuel consumption, and sensor failure can lead to continuous fuel injection, further increasing fuel consumption.
I've been running an auto repair shop for over a decade and have encountered many Changan CS35 owners complaining about high fuel consumption. The main reasons often stem from neglected maintenance. For instance, a clogged air filter restricts airflow, forcing the engine to work harder by injecting more fuel; underinflated tires increase rolling resistance, naturally leading to higher fuel usage; and old, degraded engine oil with increased viscosity reduces lubrication efficiency, making the engine labor harder. Neglecting these minor issues can lead to unnecessary fuel wastage. I recommend checking the air filter and tire pressure every 5,000 kilometers and changing the engine oil—simple maintenance that can reduce fuel consumption by 1-2 liters. Long-term neglect of these small issues may also shorten the engine's lifespan. Spending a little on regular maintenance is far more cost-effective than major repairs.
