Why is it necessary to warm up the car in winter?

Winter car warm-up is essential for engine maintenance. Due to the cold weather, the engine requires a warm-up period to gradually return to its optimal operating temperature, ensuring long-term durability. The normal operating temperature of a car engine typically ranges between 80°C and 90°C, with some high-performance engines reaching up to 100°C. After being parked overnight, the engine temperature drops to match the ambient temperature. The process of raising the engine temperature from ambient to its normal operating range is referred to as the cold start phase, which is precisely what 'warming up the car' entails.
Preheating the car before driving in winter is particularly important, especially in cold weather. Having driven for many years myself, I feel that preheating is like giving the engine a warm-up exercise, which can prevent many potential issues. In cold weather, the engine oil becomes thicker and less fluid. If you start driving without preheating, internal engine components like pistons and bearings will experience excessive friction and wear out faster. Over time, this can lead to significant damage and costly repairs. Preheating for about 30 seconds to a minute allows the oil temperature to rise slightly, improving its fluidity and making the car start more smoothly. It also reduces the extra load on the battery during cold starts. This not only extends the lifespan of the car but also makes the initial drive feel more stable, avoiding jerks or stalling. Although modern cars have advanced technology, maintaining the habit of preheating is still necessary to avoid winter driving hassles.
