[EdenMarie]

Car noise increases after an oil change due to the use of different brands of engine oil. Reasons for increased noise after an oil change: Changing to a different brand of engine oil: The reason for increased engine noise is the use of a different brand of oil. Each brand's oil formula varies, which can also affect engine noise. Carbon deposits, sludge, and fuel; incomplete fuel combustion can easily lead to carbon buildup. Carbon deposits not only increase engine noise but also affect the car's power and fuel consumption. Overfilling with oil; if too much oil is added, it can cause the engine sound to become muffled and reduce performance. Benefits of an oil change: Improving and enhancing lubrication for the engine's moving friction components, which can extend the engine's lifespan. Enhancing the engine's lubrication conditions, reducing friction in moving parts, improving the engine's fuel consumption, and increasing fuel economy.
