How long should a car warm up normally in winter?

[DiLouis]

In winter, a normal warm-up time for a car is between half a minute to one minute. During this period, the engine speed should be maintained within the range of approximately 2000 to 3000 RPM, with the speed being relatively stable without significant fluctuations, and the car body should not exhibit noticeable shaking. After this, you can drive at a low speed for 3 to 5 minutes before proceeding with normal driving. The primary reason for warming up the car is that after being parked for an extended period, the engine oil flows back into the oil pan at the lower part of the engine. Upon ignition, the upper part of the engine is initially without oil and lacks lubrication. It takes about 30 seconds after starting for the oil pump to circulate the oil to the components that require lubrication the most, such as the pistons, connecting rods, and crankshaft.
