What is the reason for Chevrolet Sail's high fuel consumption?

At present, many Chevrolet Sail owners report that the fuel consumption problem is related to road conditions, driving habits, spark plugs, killing systems and air filter elements. It is recommended that you check according to the following aspects. After the metal is worn, the clearance of other parts increases, the friction resistance increases and the cylinder pressure decreases, which will inevitably lead to oil and gas leakage. In this way, the loss increases, the efficiency decreases, the power performance decreases, and the fuel consumption of the automobile naturally increases.

1. Please have a look to see if there are high fuel consumption problems caused by road conditions and driving habits, such as fast driving speed, road congestion, heavy vehicle load and high fuel consumption. 2. Secondly, there are problems with the spark plug and high-voltage line of the gasoline vehicle, which leads to abnormal ignition circuit and high fuel consumption, which can be solved by repairing and replacing parts. 3. There is something wrong with the brake system, the brake pads don't return, and the driving resistance increases, so the fuel consumption can be reduced through repair and recovery. 4. The automobile oil circuit is not smooth, and the carbon deposit is blocked. Using fuel cleaner to clean fuel nozzle, throttle and engine carbon deposit can reduce fuel consumption. 5. The air filter element is dirty and the air is not smooth, which leads to incorrect oil-gas ratio and needs to be replaced. 6. The gasoline quality is not up to standard, resulting in high fuel consumption. 7. The metal friction surface gradually wears away, resulting in unevenness. At this time, the wear rate is several times to ten times that of a new car.
