The first is that when the weather gets cold, the fluidity of the engine oil will become worse, and the engine running resistance will increase. When the car is cold and the car is warmed up, the engine speed will be higher than in summer. It is longer than summer, and fuel consumption will increase accordingly.

The second is that when the car is running on the road, as the mileage increases, the parts will gradually wear out. It cannot be the same as when it was new. Good care and maintenance can delay the aging of the car, but wear and use All traces are irreversible and should be viewed rationally. Vibration is relatively normal and you don’t need to pay too much attention to it, but if it is obvious, you can consider replacing the throttle valve, cleaning the spark plug, replacing the fuel filter element, and cleaning the injector. If it still shakes after completing these items, consider the engine accumulation. Carbon (the carbon deposition process of EFI machines is generally very slow, the possibility is relatively low, and if you pull it at high speed regularly, the carbon deposit will be basically very small) or the machine foot pads are aging (the possibility is also very low). The first is that when the weather gets cold, the fluidity of the engine oil will become worse, and the engine running resistance will increase. When the car is cold and the car is warmed up, the engine speed will be higher than in summer, and the sound, vibration and warm-up time will be longer than in summer. , fuel consumption will also increase accordingly.

The first is that when the weather gets cold, the fluidity of the engine oil will become poorer, and the engine running resistance will increase.
