It is necessary to warm up the car after starting it in winter. Driving without warming up the car in winter can cause wear and tear on various parts of the car's engine, transmission, and other engine components, leading to a shortened lifespan; it also increases the fuel consumption of the engine, making it easier for carbon deposits to form inside the engine. Reasons for warming up the car in winter: After the car has been parked for a long time, the engine oil inside the engine flows back into the oil pan at the bottom of the engine; before the engine reaches its operating temperature, the fuel supply system, due to the low temperature, cannot effectively vaporize the gasoline completely; in a cold engine, the gear oil flows to the lower part of the transmission. Specific process for warming up the car in winter: Start the car for 30 seconds to one minute, allowing the engine's water temperature to reach the normal temperature, then you can drive. However, do not drive at high speeds at this time; maintain a low speed and do not exceed 2000 RPM. While driving at low speed, observe the water temperature gauge. If it rises slightly, you can appropriately shift to a higher gear and proceed. After driving about one kilometer, the car will be fully warmed up, and you can then drive normally.
Preheating the car after starting in winter? I think it's necessary, but it should be done in moderation. Having driven for many years, when the temperature is low in winter, the engine oil becomes thick inside the engine. Driving at high speeds directly can cause dry friction between parts, damaging them. My experience is to wait about 30 seconds after starting, allowing the oil pump to circulate and lubricate all components—this short period is sufficient. Then, drive at a low and steady speed for a few minutes, allowing the engine temperature to rise evenly and avoid overheating issues. Long idling to warm up the car? It's really unnecessary, like idling for ten or twenty minutes—it greatly increases fuel consumption and emits exhaust pollution. Although modern cars have advanced designs, the basic principles remain the same. Protecting the engine can extend the car's lifespan by several years. A related topic is slippery roads in winter; after preheating, the brake response is more sensitive for safer driving. Remember, the purpose of preheating is not to heat the car thoroughly but to prepare it for a more confident drive.
Is it necessary to warm up the car in winter? I believe the key is to balance the time. My car is relatively new, so I always wait for about half a minute after starting to let the RPM stabilize, then drive off at low speed to save fuel and hassle. In winter, engine oil is thicker, so a short warm-up allows the oil to circulate and protect the engine, preventing wear and damage to components. However, warming up for too long, such as more than five minutes, wastes fuel and increases emissions, which is bad for the environment, especially during smog season. Another related issue is that battery performance weakens in winter, and prolonged warming may drain the battery, making it harder to start the car. I suggest combining it with daily habits: while starting the car, take the time to defrost or check navigation instead of idling just to warm up. This way, you protect the car, stay eco-friendly, and reduce air pollution. Remember, driving at low speed for a few minutes heats the engine faster and more efficiently—don’t rely too much on idling.
I believe in warming up the car in winter but not overdoing it. As a pragmatist, idling too long is a waste of money: higher fuel consumption means every drop counts. 30 seconds to 1 minute of warm-up is sufficient to let the oil lubricate engine parts - cold winter oil is too viscous to flow properly, risking costly damage. Then drive gently for a few minutes to evenly warm up at lower cost. Key aspects include maintenance: timely oil changes and using winter-grade oil make warm-ups more efficient, saving money and effort. Avoid excessive idling like 10 minutes - it needlessly wastes resources, increases expenses, and raises pollution.
