Lan Se has a high fuel consumption.

Hello: Regarding your question, there are many factors that lead to high fuel consumption, such as driving habits (sudden refueling, sudden braking, neutral taxiing, overspeed gear), low tire pressure, adding inferior oil, ignition system failure, electronic control system failure, etc. These will increase the fuel consumption of vehicles. Secondly, if the vehicle is not maintained on time, such as not replacing the air filter, gasoline filter, spark plug and clutch plate in time, it will also lead to an increase in fuel consumption. Then there are carbon deposits and faults in the electronic control system, such as carbon deposits in throttle body, idle valve and fuel injector, and inaccurate signals of oxygen sensor, air flowmeter and water temperature sensor. These will affect the fuel consumption of vehicles. If the fuel consumption is too high, a comprehensive inspection is needed. If you haven't cleaned the throttle body and injector of this car, you can observe it in the test run after cleaning. After cleaning the throttle body, you need to use a diagnostic computer to reset it. The cost of cleaning these two parts is probably around 300 yuan.
