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

[GideonFitz]

In winter, the reason for warming up the car is to increase the temperature of the engine oil, which enhances its lubrication effectiveness. During winter, the outdoor temperatures are lower, and the engine oil becomes more viscous. If the oil temperature is too low, its fluidity decreases, making it difficult to fully lubricate the engine. Here are some additional details: 1. Proper warm-up method: In fact, it is not necessary to warm up the car by idling in winter. The correct way is to start the engine and then drive immediately, as this increases the engine load and speeds up the warming process. 2. Pay attention to warm-up duration: Driving immediately after starting the engine also helps the transmission oil reach its normal operating temperature faster, reducing wear on the transmission. Prolonged idling to warm up the engine can lead to increased carbon buildup inside the engine.
