What Happens If You Don't Warm Up the Car?

In winter, if the car is not properly warmed up, the engine oil tends to have higher viscosity in low temperatures, leading to poor lubrication conditions, which may result in increased fuel consumption. After warming up, the engine can achieve full lubrication and better power output. Below are the necessities of warming up the car: 1. Warming up reduces engine wear: The essence of warming up is to raise the oil and coolant temperatures of the engine, minimizing wear during operation. When a car is parked for an extended period, the oil flows back into the oil pan below the engine. Upon startup, insufficient lubrication may occur, leading to abnormal wear and potentially affecting the engine's lifespan in severe cases. 2. Engine oil lubrication takes 5 to 10 seconds: It generally takes about 5 to 10 seconds for the engine oil to circulate from the oil pan to the engine. The exact time may vary slightly depending on the vehicle model, which can be verified through daily driving. 3. The engine coolant needs to reach a certain operating temperature: During engine operation, not only does the oil require proper temperature, but the engine coolant also needs to reach a specific temperature to function correctly. Improper warming-up may cause exhaust gases to corrode the engine cylinders. 4. Besides oil, coolant temperature is also crucial: Insufficient lubrication causes wear, and when the coolant temperature is too low, chemical reactions may produce a dew point effect, which can also impact the engine. Therefore, it's advisable to ensure the engine is fully lubricated before driving.
