Why is the fuel consumption of the Sylphy getting higher and higher?
2 Answers
Here are the specific reasons why the fuel consumption of the Sylphy is increasing: 1. Affected by temperature: Temperature changes can cause fluctuations in fuel consumption. In winter, lower temperatures generally lead to higher fuel consumption. 2. Long-term lack of vehicle maintenance: Dirty engine oil and air filters can also increase fuel consumption. Dirty oil leads to poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, thereby raising fuel consumption. 3. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the ground, resulting in greater friction and driving resistance, which in turn increases fuel consumption. 4. Excessive carbon buildup in the vehicle: Carbon deposits commonly accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can lead to incomplete combustion, thereby increasing fuel consumption.
As a seasoned owner of a Nissan Sylphy, I certainly have a say. After driving 80,000 kilometers, I noticed the pedal feel wasn't quite right anymore, and fuel consumption had increased significantly. First and foremost is tire pressure – insufficient air in the tires is like running in soft-soled shoes; it's extra laborious. Secondly, there's carbon buildup, especially in direct injection engines, where sticky deposits accumulate on the fuel injectors and intake ports, making fuel injection less smooth. Then there's engine oil – if you overfill it or use oil with too high a viscosity, the engine works harder and naturally consumes more fuel. Oh, and the air filter is like a mask; when it gets clogged over time and restricts airflow, that can also drive up fuel consumption. Finally, driving habits matter – frequent hard acceleration and sudden braking without restraint will definitely burn through more fuel.
