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

[Betty]

Difficulty in cold starts during winter can be addressed by switching to engine oil suitable for winter use. Additional details are as follows: 1. Reasons for difficulty in cold starts during winter: The primary cause is the low temperature, which increases the viscosity of the engine oil, reduces its fluidity, raises engine resistance, and consequently makes starting the engine difficult. 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 in the vehicle's operating area. Note that the antifreeze level should generally be about 10 millimeters below the radiator filler cap. It's also essential to check the battery voltage. The method to check: 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 the engine barely starts, it suggests the battery voltage is low and requires charging.
