It is normal for fuel consumption to increase as the weather turns cold

As the weather turns cold, many car owners find that the fuel consumption of their vehicles has increased.It is normal for vehicles to increase fuel consumption in winter, and the main increase in fuel consumption is during idling and warming up after a cold start. After the vehicle is warmed up, in the normal driving process, the fuel consumption is actually no different from that in summer.

A slight increase in fuel consumption in winter is a normal phenomenon, because many car users usually have the habit of warming up the car, and the time of warming up the car for too long, turning on the heater and waiting for the car will increase fuel consumption. In addition, the road is slippery after cold and icy in winter, frequent braking and the overall speed is too slow to reach the economic speed (generally 60-80 km/h), which will also increase fuel consumption.

It is necessary to warm up the car before going out when the weather turns cold, but it does not take too long, and the fuel will be consumed in vain after idling for too long. Previously, a 4S shop technician specifically said that the best time to warm up the car is when the engine tachometer returns to about 800 rpm and the water temperature gauge changes slightly. However, after entering the driving state at this time, it is not advisable to accelerate with the accelerator. On the one hand, it consumes fuel, on the other hand, the warm-up of the vehicle is still not enough, and it is not good for the vehicle components. It is best to wait until the water temperature reaches 90°C, then the vehicle can drive freely.

The reason for the increase in fuel consumption may also be related to the water temperature or intake air temperature sensor, or the air flow meter, and the failure of other components of the electronic system due to low temperature causes the engine fuel consumption to increase. If the fuel consumption only increases by 1 to 2 liters, don't worry, if the fuel consumption per 100 kilometers increases by 4 or 5 liters, it is not normal. It is recommended that the owner maintain the vehicle in time, or go to a professional repair shop for overhaul.

In addition, when it comes to maintenance, car owners can consider changing to some higher-quality engine oil that is more suitable for winter. To a certain extent, the driving state of the vehicle will become smoother, and the fuel consumption will also have a good performance. The owner can pay attention to whether the spark plug needs to be replaced. Jiahangaero reminder: Especially when winter comes and some vehicles fail to ignite, apart from the dead battery, the biggest problem may appear on the spark plug. Now it is generally a model with a 4-cylinder engine, which needs to be equipped with 4 spark plugs. If any of the spark plugs has a problem, it may affect the ignition and normal driving of the vehicle, and it will also consume more fuel. At this time, replacing the appropriate spark plug will make the vehicle more powerful and save fuel consumption.
