Is Warming Up the Car Necessary?

[MacJake]

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.

From my daily driving experience, in winter mornings when I'm in a hurry to go to work, I often need to warm up the car. This way, the interior temperature rises faster, making driving more comfortable. The steering wheel isn't icy cold, and it helps defog and defrost, improving safety. However, in summer or on warm days, there's no need to waste time preheating—just start the car and go, which actually saves fuel and is more environmentally friendly. The key is to handle it flexibly based on personal habits and weather changes, rather than rigidly following rules.

Warming up the car is really unnecessary as it increases emissions, pollutes the environment, and also raises fuel consumption. Modern engine designs are advanced; driving at low gears for a few minutes after starting allows the system to heat up more efficiently, making it greener and more sustainable. I urge everyone to reduce unnecessary idling to save resources and protect the Earth's ecosystem, which is beneficial in the long run.

From a safe driving perspective, warming up the car is quite important, especially in cold weather. Preheating can quickly defrost the windshield, ensuring clear visibility, and also stabilizes engine response, reducing the risk of unexpected stalling while driving, thereby protecting personal safety. I always recommend warming up for a few dozen seconds before setting off, particularly in extremely cold regions—the difference in experience is noticeable, boosting driving confidence.
