How long should you warm up your car in the morning?

[SanAlyssa]

When driving, the warm-up time is generally about 1 minute, depending on the temperature of the day. Generally speaking, the warm-up time is based on 60 seconds. If the morning temperature is around 30 degrees, then the warm-up time should be 30 seconds (60-30=30). If the temperature is around 0 degrees, the warm-up time should be 60 seconds (60-0=60). If the temperature is around -10 degrees, the warm-up time should be 70 seconds (60+10=70), and so on, to determine the warm-up time. When the car is idling, if the engine speed is below 1000 RPM, then it can be judged that the car's warm-up is complete and it can be driven normally. The purpose of warming up the car is to allow the engine oil to circulate, thereby increasing lubrication in the engine during driving, which can reduce engine wear and increase speed.
