Why does Emgrand gl consume so much oil?

The reasons for the high fuel consumption of Emgrand gl are as follows: 1. Engine carbon deposition is serious: carbon deposition is usually formed in the nozzle, spark plug, throttle and combustion chamber. When carbon deposits reach a certain level, it will be difficult to strike a fire, slide in neutral or shift gears, slow acceleration and unstable idle speed. 2. Use inferior fuel: Because inferior fuel contains more impurities, it can't be fully burned, most of the gasoline is discharged from the car, and a layer of white or reddish-brown substance is formed on the surface of the oxygen sensor, which leads to misjudgment of the oxygen content in the exhaust gas and returns wrong data, and finally the fuel injection ratio can't be well controlled. 3. The vehicle is overloaded: there are many sundries on the vehicle. Some car owners like to put some unnecessary sundries on their vehicles, which will increase the weight of the vehicles. There are also some car owners who like to fill up with gas, which will also increase the weight of the vehicle. The greater the vehicle load, the greater the tire pressure on the ground and the greater the tire friction. 4. Using high-power electrical equipment on vehicles: Especially when idling, the generator generates insufficient power due to the low engine speed. When using high-power electrical equipment in vehicles (such as air conditioning and refrigeration, high-power influence), it will increase the burden on the engine and battery. Driving a vehicle under high load will also lead to an increase in fuel consumption.
