Is it necessary to warm up the car when the temperature is above 0 degrees Celsius?

[DeElisa]

It is still necessary to warm up the car when the temperature is above 0 degrees Celsius, but there is no need to keep idling in place. Just maintain low-speed driving for a few kilometers before driving normally. Benefits of warming up the car: The biggest benefit of warming up the car is avoiding cold engine wear. When starting the engine after it has been sitting overnight, the upper part of the engine is in a state of insufficient lubrication. It takes about 30 seconds after starting for the engine oil to reach the parts that need lubrication the most, such as the pistons, connecting rods, and crankshaft. Precautions for warming up the car: Idling to warm up the car is not better the longer it lasts. Avoid pressing the accelerator hard while idling. It is best to drive steadily at around 40 km/h for the first 2-4 kilometers. After starting the engine, wait about 30 seconds, then drive a short distance at low speed and in low gear to allow lubrication of the transmission, differential, and wheel hub bearings. Once the water temperature is normal, you can drive as usual.
