What are the reasons for the high fuel consumption of the new Sail?

The reasons for the high fuel consumption of the new Sail are as follows: 1. Clean carbon deposits: Excessive carbon deposits in the engine will lead to high fuel consumption, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaner when refueling, and after cleaning, it is best to drive the car on the highway for a while, which helps to increase exhaust volume and allow stronger airflow to carry out larger carbon deposit particles. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio of the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio of the engine, and the fuel consumption will definitely increase suddenly. When the oxygen sensor is damaged, the exhaust pipe will emit darker exhaust gas during driving, and the oxygen sensor should be replaced in time. 3. Regularly replace the three filters: During the use of the vehicle, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, they will become dirty and affect their use, and transmit wrong information to the engine control unit, causing incomplete fuel combustion and increasing engine carbon deposits.
I noticed that my new Sail has relatively high fuel consumption, probably due to my poor driving habits. I always tend to accelerate and brake sharply, stomping on the gas pedal as soon as the traffic light turns green, which suddenly increases the engine load and consumes more fuel. Also, I often leave the engine idling for too long, such as when waiting for someone by the roadside without turning off the engine, which not only wastes fuel but also increases carbon buildup. The tire pressure is often less than ideal, and when it's too low, the increased rolling resistance requires more power to drive. Recently, I've tried to drive more smoothly, avoiding sudden starts and stops, and minimizing unnecessary weight by carrying fewer items. The fuel consumption has indeed decreased significantly, saving me quite a bit of money. Remember, small habits make a big difference—developing good habits can really pay off.
My new Sail has only been bought for a few months, and after driving 3,000 kilometers, the fuel consumption suddenly increased, probably due to lack of maintenance. Last time I went for servicing, the mechanic found the air filter was clogged with dust, restricting airflow and forcing the engine to work harder, which naturally burned more fuel. After replacing the air filter and engine oil, the fuel consumption improved immediately. The tire pressure was also too low, increasing rolling resistance without me noticing. I rarely check these things regularly—if the spark plugs wear out or misfire, fuel injection can become uncontrolled. It's best to schedule regular maintenance instead of waiting for problems to arise. This week, after replacing the parts, the car feels much lighter to drive, and the fuel consumption has stabilized.
The New Sail's fuel consumption soars during peak hours in congested urban traffic, which I experience daily during my commute. The stop-and-go congestion and repeated engine start-stop cycles drastically increase fuel usage. When the weather turns cold and the heater is turned on, the added load from the air conditioning system makes the engine work harder, consuming even more fuel. Additionally, frequent heavy loads, like a fully packed trunk, make the car struggle during acceleration. At high altitudes or in windy conditions, thin air and increased wind resistance also contribute to higher fuel consumption. While these external factors are hard to change in the short term, measures like using the air conditioning less and coasting more can help alleviate the issue.
