What Causes Loud Noise When Accelerating the Car?
1 Answers
Possible reasons for loud noise when accelerating the car include a loose exhaust pipe, excessive engine oil, incorrect engine oil type, or internal engine issues. Loose exhaust pipe: If the exhaust pipe connected from the air intake grille to the air filter is loose, it will produce loud noise when accelerating. The pipe should be secured with tape. Excessive engine oil: Adding too much engine oil increases resistance when the car is under load, reducing power output and causing louder noise during acceleration. Always monitor the oil level when refilling. Incorrect engine oil type: Using the wrong oil type can severely damage the engine and cause loud noise when accelerating. Never mix different oil types or use incompatible oil. Internal engine issues: These may lead to exhaust pipe blockage, resulting in louder noise during acceleration. Owners should promptly visit a 4S shop for inspection.
