Do Cars Need to Warm Up Before Starting?
1 Answers
For modern fuel-injected cars, prolonged warm-up is unnecessary. Here are the details: 1. Extended warm-up periods increase fuel consumption, though this should be determined based on local temperatures. In colder northern regions, warming up the car is still necessary, while in hot areas like Hainan, it's not required. Whether to warm up your car should be decided based on your specific circumstances. 2. The correct warm-up method is to start driving within 30 seconds to one minute after ignition. However, avoid high-speed driving during this period; maintain low speeds with engine RPM not exceeding 3000~3500, typically keeping it around 2000 RPM. Otherwise, the intense wear on the engine and transmission caused by aggressive driving cannot be reversed. Once the engine reaches its normal operating temperature, you can resume your "personal driving habits."
