Auto start-stop does not harm the car. The start-stop function only stops the engine from working, but the oil system does not stop. This means that even though the engine is not running, the oil will still circulate inside the engine, ensuring better lubrication when the car starts again and protecting the engine. The auto start-stop system is a system that can automatically control the engine's shutdown and ignition, known in English as STOP&START, abbreviated as STT. Vehicles equipped with engine auto start-stop technology will automatically shut off the engine when temporarily stopping during driving. When it's time to move forward again, the system will automatically restart the engine. Generally, the auto start-stop function is enabled by default in vehicles, but owners can choose to turn it off if they don't need it. Pros and cons of the auto start-stop system: Pros: Fuel savings; Whether waiting at a red light or stuck in traffic, the engine auto start-stop technology can automatically turn off the engine when the car stops, achieving the goal of saving fuel. Cons: Increased vehicle costs; Cars with an auto start-stop system are several thousand dollars more expensive than those without. Additionally, due to the frequent starting and stopping of the engine, there is a higher demand for oil quality, leading to further increases in maintenance costs.
