What Causes Exhaust Pipe Abnormal Noise?

[MacMadelyn]

The causes of exhaust pipe abnormal noise are as follows: Failure to change engine oil regularly: Conventional engine oil needs to be replaced every 5,000 kilometers, while higher-quality full synthetic oil must also be replaced after 7,000 to 8,000 kilometers. It is essential to change the oil on time and develop the habit of frequently checking the oil dipstick. Incorrect engine oil grade: It is best to use the same oil grade as the original factory oil. Avoid adding different oil grades arbitrarily, as different oil grades represent different oil viscosities. Oil that is too thin or too thick can cause increased engine noise. Shock absorber malfunction: Everyone knows the role of shock absorbers. Generally, you can feel the quality of the vehicle's shock absorbers when going over speed bumps. When there is a problem with the vehicle's shock absorbers, it can lead to increased engine noise.
