What's the buzz when the seventh-generation Accord refuels?

There was a buzz when the Accord VII refueled, but there was no reason after receiving the oil. Please help me to interpret it. There was a buzz when the Accord VII refueled, but there was no reason after receiving the oil. Please help me to interpret it. The reasons why the automobile engine hums when refueling the valve are: 1, and the engine oil is not fully lubricated to all parts of the engine. After running for a period of time, new engine oil can be evenly lubricated to all parts of the engine. 2. If it doesn't improve after a period of time, it may be seriously worn, and then clean the inside of the engine to make the wear gap bigger. 3. If the gap is large and the seal is not good, the condition of the engine will get worse and there may be noise. It is recommended to go to the repair shop for inspection. 4. If you don't pay attention to maintenance, it may be that the machine has too much carbon (too much carbon in the engine, too much carbon in the throttle, too much carbon in the spark plug, etc.). ). Just go to the repair shop and clean it. 5. It may also be caused by poor filtration (the most common is that the air filter is too dirty). Go to the repair shop for cleaning or replacement. @20 19
