1 Answers
Here are the reasons for excessive noise in a car: 1. The engine oil viscosity is too high; 2. Carbon deposits in the cylinders; 3. Aging of engine mounts; 4. Aging tires. Additional information: Solutions to reduce car noise include: 1. The most noticeable change in noise is engine noise, especially in vehicles that have not been maintained for a long time, where the noise is particularly evident. Regular vehicle maintenance is recommended. 2. For the engine, if overly viscous engine oil is used, it can result in insufficient oil flow into the hydraulic lifters, causing valve noise and generating noise. In this case, it is necessary to switch to a relatively lower viscosity gasoline.
