Do small cars need to warm up in winter?

[AugustLee]

Small cars need to warm up in winter. Not warming up the car can cause damage to the vehicle: it leads to engine wear as the engine oil settles at the bottom when the car is cold, leaving the engine internals in a state of dry friction. The method to warm up the car is: after starting the vehicle, let it idle for 1 to 2 minutes to allow the engine coolant to reach normal temperature before driving. The benefits of warming up the car are: 1. After the car has been parked for a long time, the engine oil flows back into the oil pan, leaving the upper part of the engine lacking lubrication; warming up helps lubricate it. 2. When the engine has not reached its operating temperature, the fuel system cannot effectively vaporize gasoline completely due to the low temperature; warming up improves efficiency. 3. It helps the transmission gear oil to lubricate the upper part of the transmission.
