Is it normal to increase fuel consumption in winter?

It is normal for fuel consumption to increase in winter.

One of the main reasons for high oil consumption in winter is that the thermal efficiency of gasoline decreases due to temperature.

Generally speaking, the working temperature of the engine needs to be maintained at about 80-90 degrees. If the temperature is too high, the cooling system of the engine will automatically increase the water circulation speed, increase heat dissipation and take away excess heat. On the contrary, reduce the circulating speed of cooling water and keep the necessary temperature.

In winter, the temperature of the engine is not easy to keep around 80 degrees, so the engine will increase the fuel injection and change the ignition advance angle to keep the temperature.

At the same time, the thermal efficiency of gasoline in cold weather is much lower than that in summer. These factors naturally make the fuel consumption of cars in cold weather in winter higher than in other seasons.

How to solve the problem of increasing fuel consumption in winter?

1, regularly check the tire pressure and wear degree. Insufficient tire pressure or serious wear will increase fuel consumption.

2. Replace the spark plug in time. The damage of spark plug will reduce the ignition energy, slow down the vehicle speed and lead to an increase in fuel consumption.

3. Changing the winter oil during maintenance can reduce the internal resistance of the engine. The temperature in winter is relatively low, especially in the north, which is basically above-10℃. In low temperature weather, the lubrication effect of the engine will decrease, which will lead to an increase in resistance, thus increasing fuel consumption.

4. Turn off the air conditioner switch of the air conditioner while driving.

5. Reduce the load of the car, clean the trunk regularly, and don't put unnecessary sundries in the car.
