What to Do When a Car Has Difficulty Starting in Cold Winter?

[DylanDella]

Difficulty starting a cold car in winter can be addressed by switching to engine oil suitable for winter use. Additional information is as follows: 1. Reasons for difficulty starting a cold car in winter: The main reason is the low temperature, which increases the viscosity of the engine oil, resulting in relatively poor fluidity. This increases engine resistance, making it harder to start the engine. 2. Other considerations: Car owners should check the freezing point of the antifreeze. The liquid freezing point of the antifreeze should be 5 to 10°C lower than the lowest temperature of the vehicle's operating area. Note that the antifreeze level should generally be about 10 millimeters below the radiator filler opening. Additionally, check the battery voltage. Inspection method: With the engine at normal temperature and the starter in good condition, if the engine starts smoothly several times in a row, it indicates the battery is in good condition with normal voltage. If each start results in a gradual decrease in engine speed, or if the engine barely starts, it indicates the battery voltage is in a depleted state and should be charged.
