Warming up the engine

Bringing it to operating temperature is very good because it can help extend the engine's lifespan and greatly reduce wear and tear when the engine is at low temperatures. This is because engine parts are made from various metals, especially moving parts, which need to receive an appropriate level of heat.

Just like how humans need to warm up before playing sports

to avoid injuries from exercise, such as muscle cramps, muscle inflammation or tears, and abnormal breathing or heart function. Instead of warming up in place, we can switch to walking slowly and gradually increasing speed until it reaches a normal running pace. Similarly, with cars, we must stop idling to warm up the engine. Besides wasting fuel, it also increases air pollution.

The appropriate action nowadays is: once the engine starts and warning lights turn off, you can drive off immediately, but you must drive at a slow speed for a while until you see the engine temperature gauge rise to about half of the normal temperature. Then, you can gradually increase your speed. Doing this is like warming up by moving slowly and then gradually increasing speed until it reaches a normal level. This can help prevent injuries from exercise, just like with an engine. This type of warm-up is sufficient to extend the engine's lifespan. The important thing is that it efficiently helps reduce waste and pollution 

• When the engine starts and all warning lights turn off, slowly start moving 

until you see the engine temperature gauge rise to about half of the normal temperature, then you can gradually increase your speed. 

Doing this... 
is like warming up the human body by moving slowly, then gradually increasing the speed until it reaches a normal level. This can help prevent injuries from exercise, just like with an engine...

Because... this type of warm-up is sufficient to extend the engine's lifespan. 
• The important thing is... it efficiently helps reduce fuel consumption and pollution. 

The era of idling to warm up the engine is over. Besides wasting fuel, the most important thing is that it also causes pollution from your car's exhaust.
