Should the car be in P gear or N gear during warm-up?

During car warm-up, it should be in P gear. The warm-up should not exceed 60 seconds, and after starting, avoid high-speed driving. The engine speed should not exceed 2000 RPM. Increase the RPM only after the coolant reaches the appropriate temperature. This helps better protect the car engine from damage. The need for warm-up arises because after the engine has been stationary overnight, the lubricating oil on various friction surfaces has mostly dissipated, losing its protective oil film. The normal operating temperature of a car engine is between 80 to 90 degrees Celsius. In winter, after being parked overnight, the engine temperature is relatively low. The process of the engine warming up from cold to the required operating temperature is known as warm-up. Warm-up is necessary not only in winter but also in summer, requiring appropriate warm-up during that season as well.
