1. Extra fuel consumption
There are three aspects to the extra fuel consumption: one is that the temperature in winter is too low, the engine needs more heat to do work, so the fuel consumption is naturally high; the other is that the viscosity of the oil is higher in winter, and the temperature of the engine body is low, which makes the fuel atomized If it becomes worse, part of the non-combustion oil is drained; third, the engine cannot maintain the normal working temperature due to the cooling water circulation taking away part of the heat, so the normal operation can only be maintained by increasing the fuel injection amount.
2. Heater fuel consumption
Many car owners think that blowing hot air is more fuel-efficient than blowing cold air, but this is not the case. Theoretically, the hot air only needs to send the hot air from the engine water tank into the cab without starting the air conditioner compressor to warm the car. Therefore, many people feel that this heat is already there, there is no additional energy consumption, and there should be no additional fuel consumption.
However, the temperature is low in winter. If the heating is turned on, the engine needs to provide additional heat in addition to heat preservation. At the same time, in order to maintain the working temperature, the engine needs to increase the amount of fuel injection, so the fuel consumption becomes higher.

3, tires cause oil loss
The tires do not consume fuel in normal times, but in winter, the temperature is low, and the air pressure in the tires cannot be properly adjusted, which increases the friction of the tires and increases the fuel consumption. Therefore, it is recommended that car owners who use all-season tires can increase the tire pressure by 0.2-0.3Bar in winter.
In addition to the above reasons, the reasons for high fuel consumption in winter include idling hot cars, uninterrupted operation of electronic fans, and failure of water temperature sensors. After knowing the reasons for these fuel consumption, let’s take a look at some fuel-saving tips.
1. Check the tire pressure and wear degree on time;
Second, timely replacement of spark plugs;
3. The warm-up time should not be too long, about 30 seconds to 1 minute, and then warm the car when driving slowly. After one or two kilometers, the engine will reach the working temperature;
4. Use gasoline with high cleanliness. Such gasoline is not easy to form carbon deposits and can effectively reduce fuel consumption. Therefore, high-quality gasoline should be added when refueling;
5. When the car is running at high speed, the air resistance will increase, so the fuel consumption will also increase.
6. Keep driving at a constant speed, because frequent sudden acceleration and sudden braking will increase fuel consumption.
