Why does the car feel noisier after maintenance?
2 Answers
There are several reasons why a car may feel noisier after maintenance: 1. The quality of the engine oil itself may be problematic; 2. Too much engine oil may have been added; 3. The type of engine oil selected may be inappropriate, as both excessively high or low viscosity can increase noise. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. The benefits of car maintenance include: 1. Ensuring the vehicle is in excellent performance condition; 2. Improving the vehicle's efficiency and reducing the wear of its parts and tires; 3. Enhancing driving safety; 4. Preventing vehicle issues that could lead to hazards; 5. Reducing noise and environmental pollution; 6. Keeping the vehicle's appearance clean and preventing damage.
After the maintenance, I feel the noise has increased, and I think it might be due to the oil change. Sometimes, using the wrong oil type or overfilling the oil can make the engine run louder, especially in the first few dozen kilometers after the oil change. Additionally, improper installation of the oil filter may restrict oil flow, causing the engine to bear extra load and produce additional noise. If the tire pressure was adjusted during maintenance, higher pressure can also significantly increase rolling noise. It's also worth considering whether any parts are loose, such as chassis screws not being tightened properly during maintenance, which can cause rattling noises. I suggest you first check the oil dipstick and tire pressure to see if they are normal, then pay attention to the source of the noise. If you're still unsure, it's safer to go back to the repair shop for a recheck to avoid minor issues turning into major ones that could affect driving safety.
