Why is it difficult to start a car in low temperatures?

[Leah]

In winter, low temperatures make it difficult to start a car mainly due to reduced battery capacity and slow oil flow. The specific reasons are as follows: Battery discharge issues: The durability of the battery decreases in winter. Since lead-acid batteries are used, their discharge time is affected by temperature. The lower the temperature, the shorter the discharge time, causing the battery to consume much more power than in other seasons. Slow oil flow: Winter temperatures are low, especially in northern regions. The viscosity of engine oil increases as the temperature drops, slowing its flow and increasing engine resistance, making it difficult to start the vehicle. A professional winter maintenance service can be performed, including changing to engine oil suitable for the local climate.
