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

[MacTimothy]

In cold weather, warming up your car for 30 seconds to 1 minute is sufficient. The correct method to warm up your car is: 1. Start the vehicle and keep the air conditioning turned off; 2. Let the engine idle for 30 seconds to 1 minute; 3. Begin driving slowly once the engine runs smoothly; 4. Once the engine coolant temperature gauge rises by 1 to 2 bars, you can drive normally and turn on the air conditioning. The reasons for warming up your car are: 1. After prolonged parking, the engine oil flows back to the oil pan at the bottom of the engine; 2. Before reaching operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to lower temperatures; 3. Gear oil flows to the lower part of the transmission when parked, leaving the upper part of the transmission unlubricated when cold.
