Does the Auto Start-Stop Function Harm the Engine?

Auto start-stop function has a certain impact on the engine, but the impact is very minimal and does not affect the engine's service life. When car manufacturers produce engines with auto start-stop, the designed lifespan of the auto start-stop function is 500,000 cycles. Even if it starts 100 times a day, it would take about 17 to 18 years to reach that limit. The real significant impact on the engine occurs during cold starts, when the oil circuit and engine oil are circulating. Auto start-stop involves hot starts, where the engine already has oil lubrication. Therefore, even frequent start-stops cause minimal wear to the engine. The start-stop function only stops the engine from working, but the oil system continues to operate, ensuring better lubrication when the car starts again, which also helps protect the engine.
