What are the reasons for the high fuel consumption of the Emgrand GL?

[EvelynMarie]

The reasons for the high fuel consumption of the Emgrand GL are as follows: 1. Severe engine carbon deposits: Carbon deposits usually form on the fuel injector, spark plug, throttle valve, and combustion chamber. When carbon deposits reach a certain level, symptoms such as difficulty in ignition, stalling during neutral coasting or gear shifting, weak acceleration, and unstable idle speed (fluctuating high and low) will occur. 2. Use of inferior fuel: Inferior fuel contains more impurities and cannot be fully burned, so most of the gasoline is discharged from the vehicle. At the same time, the oxygen sensor forms a layer of white or reddish-brown substance on the surface, leading to misjudgment of exhaust oxygen content measurement, transmission of incorrect data, and ultimately poor control of the fuel injection ratio. 3. Excessive vehicle load: Having too many miscellaneous items in the vehicle will increase the weight. Filling the fuel tank to the brim will also increase the vehicle's weight. The greater the vehicle load, the greater the pressure of the tires on the ground, and the greater the tire friction.
