Baojun 5 10 engine is noisy. Is there any way to maintain and improve it?

There are many reasons for engine noise. It's best to check it first, such as air intake, ignition, throttle, abnormal sound of parts, oil quality, etc. Air intake generally refers to whether the air filter element needs to be replaced or blocked. Ignition is a spark plug, and the throttle should be cleaned in time. Finally, the quality of the oil used is a problem. If you use ordinary engine oil, the engine will naturally have noise, such as GT? Magic? Force? Red is a high-quality all-synthetic engine oil. With the addition of liquid molybdenum, it has a good protective effect on the engine, and the engine will naturally be much quieter.
