How to Properly Warm Up an Automatic Transmission Car?

First, it is necessary to get the engine running. Run the engine for thirty seconds to 1 minute before driving. When starting off, drive at low speed for a while to allow the system to reach normal operating temperature before driving at high speed. After the engine temperature rises to the normal level (approximately 3 to 5 minutes), you can resume normal driving. The purpose of warming up the car is to bring the engine temperature to around 90 degrees, so that the relative temperature inside and outside the entire engine can approach the ideal state.
I've been driving automatic transmission cars for twenty years, and the practice of warming up the car has changed significantly. In the past, everyone said to idle for a few minutes to let the engine warm up, but now with advanced designs in new cars, the correct method is to start the engine and wait for ten to twenty seconds to allow the oil pump to circulate oil and lubricate the engine, then shift to D gear and drive slowly for five minutes at low speed. Avoid sudden acceleration or high RPMs until the water temperature is normal, keeping it below 2,000 RPM. This method warms up the engine faster, reduces cold wear, extends the life of parts, and is also fuel-efficient and environmentally friendly. Even in northern winters, I just wait a few dozen seconds longer, but the car warms up faster during driving. Remember not to idle for too long, as it wastes gasoline and may cause carbon buildup issues. The transmission oil warms up with the engine and doesn't require special treatment. Making this a habit every time ensures good car maintenance.
I just bought a new automatic car and researched the warm-up issue. Simply put, don't idle and wait after starting. The correct way is to fasten your seatbelt and organize your things while the engine starts, taking about ten seconds for the oil system to activate. Then, shift into gear and drive, but keep the speed steady and drive slowly for the first few minutes. The engine reaches normal temperature faster under driving load, reducing mechanical friction and protecting the engine. Modern cars have intelligent systems that optimize the startup process, making idling to warm up an outdated method that wastes resources and is not eco-friendly. I've never had any issues—it saves money, is efficient, and reduces exhaust emissions. In cold weather, wait a bit after starting, but driving warms the engine quickly, making daily commutes convenient. Developing this good habit ensures long-term vehicle use.
I drive an automatic transmission car to take my child to school every day, and warming up the car is quite simple. After starting the car, wait about 15 seconds before driving to allow the oil to circulate and lubricate the engine, then drive out slowly keeping the speed low for the first one or two kilometers. Only accelerate after the temperature gauge shows normal readings to avoid engine damage. This method is safe and practical, reducing cold-start issues and saving on maintenance costs. Modern cars only need this treatment—idling for too long just wastes fuel.
