Why is it hard to start a car in winter?

[DiFrank]

The reasons and solutions for why it's hard to start a car in winter are as follows: 1. The battery's capacity decreases due to the cold weather, leading to power loss or insufficient charge if the car hasn't been driven for a long time, resulting in difficulty starting. In this case, simply recharge the battery. 2. The lower the temperature in winter, the higher the viscosity of the engine oil, which reduces its fluidity and increases engine resistance, making it harder to start the car. To address this, you can change the oil and use engine oil with lower viscosity. Additionally, check if the fuel filter is clogged, and replace it with a new one if necessary. 3. Excessive carbon buildup can also make starting difficult. Carbon deposits typically accumulate in key areas such as the fuel injectors, combustion chamber, and valves. If not cleaned in time, they can affect the car's performance and increase fuel consumption. A simple and practical way to clean carbon deposits is to add some additives to the gasoline, such as professional fuel system cleaners.
