Increased engine noise is related to engine oil. Improper use of engine oil, such as using a viscosity that does not match the engine, can easily lead to carbon buildup, resulting in louder engine noise. Solution: Use the oil grade specified in the vehicle manual and avoid mixing different brands of engine oil. Generally, loud engine noise is caused by carbon buildup. Here are several specific reasons for increased engine noise: 1. Aging or loosening of engine mounts. Engine mounts are rubber blocks between the engine and the frame. Solution: Tighten or replace the engine mounts. 2. Improper use of engine oil. Using oil with a viscosity that does not match the engine can easily cause carbon buildup, leading to louder engine noise. Solution: Use the oil grade specified in the vehicle manual and avoid mixing different brands of engine oil. 3. Engine misfire. An engine misfire occurs when one or more cylinders are not functioning properly. Solution: Check the condition of each ignition coil and spark plug in the cylinders.
