Southeast V3 cars are very expensive recently. What should I do?

If the vehicle is not maintained on time and the air filter, gasoline filter, spark plug and clutch plate are not replaced in time, the fuel consumption will increase invisibly. Electronic control system also has carbon deposits and faults, such as throttle valve, idle valve and fuel injector. In addition, the inaccurate signals of oxygen sensor and water temperature sensor are also a factor of fuel consumption. Of course, driving habits, such as sudden refueling, sudden braking, and inconsistent speed and gear are also one of the reasons for fuel consumption. Low tire pressure and adding inferior oil products will also increase vehicle fuel consumption. If the fuel consumption is too high, please check it comprehensively.
