Oil consumption suddenly increases in winter, and suggestions are urgently needed.

If the vehicles did not collide, the chassis was deformed, which was mostly caused by the altar. Cleaning throttle, intake manifold, fuel injector and three-way catalyst can be improved. At the same time, check the working conditions of spark plug and cylinder block. Whether the engine oil meets the applicable winter label. Generally, due to the low temperature in winter, after the cold start of the vehicle, the atomization effect of gasoline is not good, the combustion is not sufficient, and the fuel utilization rate is reduced. When the water temperature reaches 90 degrees, try to avoid using electrical equipment and increase the burden on the engine. Such as air conditioning. After replacing the snow tires, the resistance also increases.

Another thing that needs to be checked is the auxiliary braking system and the hand brake. Many drivers' brake designs are unreasonable, because the snow and ice weather will freeze the brake lines. Although the handbrake is released in the car, the rear of the car is still not in an automatic state, so driving will increase resistance and fuel consumption.
