2 Answers
Engine auto start-stop does not harm the engine, but it has a greater impact on the starter motor and battery. Here are the detailed explanations: Reasons why auto start-stop does not damage the engine: The engine auto start-stop is mainly used for brief stops, such as waiting at traffic lights. During this time, the engine temperature is normal, and the oil and various lubrication systems are also in normal condition, so the wear on the engine is negligible. Impact of auto start-stop on the starter motor and battery: The starter motor experiences increased wear during frequent starts, which reduces its lifespan. Additionally, it places a significant load on the vehicle's battery, so regular checks of the starter motor and battery are necessary.
As a frequent city commuter, I've been using the auto start-stop feature in my car for nearly three years, and the engine has been running perfectly. The manufacturer reinforced the starter and lubrication system during design, ensuring smooth starts. The fuel-saving advantage is particularly noticeable; it reduces fuel consumption during prolonged idling in traffic, saving me dozens of dollars on average each month. Although the battery might need replacement earlier, requiring a check every two years, overall, it doesn't harm the engine. The key is to maintain regular maintenance, clean carbon deposits, and inspect the battery, avoiding using the start-stop feature in harsh weather or on steep slopes. Modern cars have undergone countless tests, proving that start-stop causes minimal engine wear—don't fear it. Focus more on actual driving habits, avoid aggressive acceleration, and let the feature work naturally for a worry-free and eco-friendly experience.
