How Often Should a Car Be Started in Winter?

[JosephineFitz]

In winter, a car should be started every five days. Cold winter weather requires proper car maintenance, with engine oil being a key aspect that needs regular replacement. Effects of not driving the car for extended periods in winter: 1. Engine oil is prone to deterioration, and the acidic substances produced can damage the engine, causing corrosion; 2. Prolonged inactivity can reduce tire lifespan and accelerate aging; 3. Long-term parking can lead to battery drain, making the car unable to start; 4. The engine and transmission may not receive sufficient lubrication, leading to internal part rusting; 5. Extended parking can also cause brake disc rust.

I think this is a pretty common issue, especially for those who drive less in winter. Based on my experience, if the car is left unused, it's best to start it once a week and let it run for about 10 to 15 minutes each time. This helps maintain the battery's charge. In low temperatures, the battery is prone to discharge or even freeze, and regular starting can prevent breakdowns on the road. Additionally, engine oil thickens in cold weather, so starting the engine allows the oil to circulate, reducing the risk of wear. If you live in an area with frequent snow or sub-zero temperatures, like northern regions, you might need to do this more often, say every 5 to 7 days. Another tip is to use a smart charger when the car is parked for long periods—it's more convenient than manual starts. In short, don't start the car just for the sake of it; adjust based on weather and driving habits to protect the car and save energy.

As an average car owner, I pay special attention to winter car maintenance. My routine is to start the car every three days or so when not in use, letting it run for 8 to 10 minutes. Once I forgot, and the battery died, forcing me to call for a jump start—costly and troublesome. Low temperatures reduce battery performance and can cause engine component issues; starting it periodically ensures everything runs smoothly. However, avoid doing it too frequently, like daily, as that wastes fuel and increases emissions. I also check the lights and tire pressure for safety. I recommend downloading a weather app to adjust the starting frequency based on temperature: more often below freezing, less often when warmer.

From a technical perspective, car batteries discharge faster in cold winter temperatures, and the engine requires lubrication for cold starts. I recommend starting the engine once a week for about 10 minutes if there are no driving plans, as this helps recharge the battery and maintain the system. The colder the temperature, the shorter the interval should be; for example, at -10°C, it may be necessary to start the engine every 5 days. The key factor is the battery's condition, with older batteries requiring extra caution. Regular engine starts can also prevent other issues, such as fuel system blockages.
