How to Solve the Issue of Nissan Sunny Consuming 10L/100km?

[Rachel]

Here are the solutions for the Nissan Sunny consuming 10L/100km: 1. Tires: Fuel consumption is significantly related to tires. Generally, the larger the contact area between the tires and the ground, the stronger the grip. However, this also means greater frictional resistance. 2. Oxygen Sensor: The primary function of the oxygen sensor is to monitor the oxygen concentration in the exhaust. The vehicle's computer adjusts the fuel injection quantity in real-time based on the data it provides. It is usually installed near the three-way catalytic converter, divided into the front oxygen sensor and the rear oxygen sensor. 3. Carbon Deposit Issue: Carbon deposits inside the engine can cause unstable idle vibrations and reduced machine efficiency, leading to increased fuel consumption. Carbon deposits mainly adhere to areas such as the intake tract, intake and exhaust valves, piston tops, spark plugs, fuel injectors, and throttle valves. 4. Poor Driving Habits and Road Conditions: Poor driving habits are also a reason for increased fuel consumption. Examples include sudden acceleration, sudden braking, sudden stops, prolonged idling, speeding, frequent lane changes; for manual transmission vehicles, delayed gear shifting, and driving at high speeds in low gears, etc.
