How many minutes is appropriate to warm up the car in winter?

[IsabellaDella]

It is appropriate to warm up the car for 1 to 2 minutes in winter, allowing the engine coolant temperature to reach normal operating temperature before driving. The reasons for warming up the car in winter are: 1. After prolonged parking, the engine oil flows back into the oil pan at the bottom of the engine; 2. Before the engine reaches operating temperature, the fuel injection system cannot effectively vaporize gasoline completely due to low temperature; 3. In cold conditions, gear oil flows to the lower part of the transmission. The consequences of not warming up the car in winter include: 1. Increased wear on the engine, transmission, and various engine components, leading to reduced lifespan; 2. Higher fuel consumption in the engine, making it more prone to carbon buildup inside the engine.
