Is it necessary to warm up the car before driving?
2 Answers
Starting the car requires warming it up. Here is more relevant information: 1. Reasons: After starting the car, let it idle for about a minute. When the car has been stationary for a long time, the engine oil inside the engine slowly settles to the bottom, leaving the engine components without lubrication. 2. Tips for warming up the car: After starting the car, you will notice the engine speed is around 1200 RPM. After about a minute, the speed will drop to around 800 RPM, indicating the warm-up is complete. How long should you warm up the car before driving? Once this signal appears, you can start driving. Otherwise, it may lead to increased carbon buildup in the engine, which can be more damaging than not warming up the car at all.
I remember older generation drivers always said you need to warm up the car for several minutes in winter to protect the engine. But after driving for over a decade, I've found modern vehicles really don't require that hassle. After starting the engine, I usually wait about half a minute for the oil to circulate, then drive gently - this way the engine warms up faster and more efficiently while moving. Prolonged idling just wastes fuel, increases emissions, and offers no real benefit to the engine. I've checked the manuals - modern cars have optimized electronic fuel injection systems and advanced oil formulations, making even sub-zero temperature startups safe after brief idling. The key is gentle acceleration initially, avoiding hard throttle to prevent cold-start wear. Of course, in extreme cold regions a slightly longer wait is acceptable, but overall excessive idling is counterproductive. Developing the habit of driving off promptly saves fuel and is more environmentally friendly.
