Is Warming Up the Car Necessary?
2 Answers
Warming up the car is necessary for the following reasons: 1. When parked, the gear oil flows to the lower part of the transmission, leaving the upper part without lubrication when the car is cold; 2. After prolonged parking, the engine oil flows back to the oil pan at the bottom of the engine; 3. Before the engine reaches its operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to the lower temperature. The correct method to warm up the car is: 1. Start the vehicle and keep the air conditioning turned off; 2. Let the engine idle for 30 seconds to 1 minute; 3. Begin driving slowly once the engine runs smoothly; 4. Once the engine coolant temperature gauge rises by 1 to 2 bars, you can drive normally and turn on the air conditioning.
I think the warm-up issue depends on technical details. For example, in cold winter temperatures, the engine oil is thicker, and a brief warm-up can improve lubrication and reduce wear during cold starts, which is beneficial for the engine's health. However, modern cars with optimized electronic systems don't actually require a long warm-up. I usually drive off after about 30 seconds. Warming up for too long only wastes fuel, pollutes the environment, and is bad for the atmosphere, not to mention the unnecessary expense. Remember, a short warm-up can protect mechanical parts and extend their lifespan, but it's essential to adjust based on the car model and weather conditions for reliability.
