How Long Should You Warm Up Your Car in Cold Weather?

[MariaMarie]

Generally, idling for about 3 minutes is sufficient. The reasons for warming up your car are as follows: 1. The primary purpose is to prevent components from working intensely before the engine oil returns to position. After prolonged parking, most of the engine oil inside the car flows back to the oil pan. During a cold start, the oil cannot immediately reach the surfaces of various engine parts to form an effective oil film. If you drive off immediately after starting the car, it can accelerate engine wear. 2. Before the engine reaches its optimal operating temperature, the fuel supply system, due to the low temperature, cannot effectively vaporize gasoline completely. Liquid gasoline vaporizes when its temperature rises to the boiling point. The optimal operating temperature for an engine is between 80-90 degrees Celsius. At this temperature, the gaps between engine components are ideal, the oil temperature is most conducive to flow, efficiency is highest, fuel consumption is lowest, and the power output is maximized.
