What is the correct way to warm up a car?

The correct way to warm up a car: Let the engine idle for about 1 minute, then drive slowly until the water temperature reaches normal levels, which completes the warm-up process. During slow driving, maintain a low speed and keep the engine RPM below 3000 to 3500. Avoid stepping hard on the accelerator (except in special circumstances), as this can cause significant damage to various parts of the engine. The key to warming up a car is not just idling but the slow driving after idling. The reason for not idling for too long is that lubricants for various components only become fully active when the car is in motion. Additionally, systems like the steering, braking, differential, and suspension require some movement to adapt to working conditions.
As a veteran driver with over 20 years of experience, I've found that the key to warming up a car is keeping up with the times. In the past, it was common practice to let the car idle for ten minutes after starting, but things are different now. With advancements in modern engine technology, oil pumps and electronic systems work much faster. It's now recommended to let the car idle for no more than 30 seconds to a minute after starting, allowing the oil to circulate sufficiently, then gently press the accelerator and drive off slowly. For the first few kilometers, avoid sudden acceleration or high RPMs, and wait until the temperature gauge needle reaches the middle zone before driving normally. This not only protects the engine by reducing wear but also saves fuel, especially in cold winters when prolonged idling can actually increase the risk of freezing damage. Consistently following this practice keeps the car in better condition and extends the lifespan of its components.
