How Long Should You Wait Before Driving After Starting the Car?

Warming up the car should take about 30 seconds to one minute after starting before driving. However, avoid driving at high RPMs during this time. Maintain a low speed, keeping the engine RPM below 3,000–3,500, ideally around 2,000 RPM. Driving aggressively at this stage can cause irreversible damage to the engine and transmission due to excessive wear. Once the engine reaches its normal operating temperature, you can resume your usual driving habits. Reasons for warming up the car include: Lack of Lubrication: After the car has been parked for an extended period, the engine oil flows back to the oil pan at the bottom of the engine. When starting the engine after prolonged inactivity (e.g., overnight), the upper part of the engine lacks lubrication as there is no oil present. Inefficient Fuel Vaporization: Before the engine reaches its optimal operating temperature (approximately between 90–110°C), the fuel system cannot effectively vaporize gasoline due to the low temperature. Transmission Gear Lubrication: Lubrication of the transmission gears is often overlooked and poorly understood. Similar to engine oil, transmission fluid settles at the bottom of the transmission when cold. Only when the car is in motion does the fluid circulate, lubricating the upper parts of the gears.
I remember when I was young driving old cars, I always used to let the engine warm up for over ten minutes after starting, saying it was to let the lubrication work. Now with upgraded car technology, lubrication systems have improved greatly. Within seconds of starting, the oil can circulate throughout the engine, so you can shift into gear and drive off right away with no problem. In cold weather like winter, waiting half a minute for the oil to warm up slightly is enough. At normal temperatures, there's no need to waste that time. I've tried driving off immediately for years—it saves fuel and is more environmentally friendly, avoiding unnecessary idling emissions. Modern car manuals also advocate this practice, saving time and hassle while extending component lifespan, just don’t stomp on the accelerator when starting. In short, the sooner you drive off after starting, the better. Once you get used to it, it really feels convenient.
