What is the correct way to warm up a car in the morning?

After starting the vehicle, let it idle for 1 to 2 minutes to allow the engine coolant to reach normal operating temperature before driving. Below are the functions of warming up the car: Lubrication: After the car has been parked for an extended period, the engine oil flows back into the oil pan, leaving the upper part of the engine in a state of insufficient lubrication. When the engine is cold, the gear oil flows to the lower part of the transmission. Only when the car is moving does the operation of the gears bring up the gear oil from the bottom. Warming up the car serves a lubricating function. Reaching operating temperature: When the engine has not reached its operating temperature, the fuel supply system, due to the low temperature, cannot effectively vaporize the gasoline completely.
