In Hutu physical store, we added Huangxing engine oil, the winning brand with abnormal engine sound.

Causes of abnormal engine noise caused by adding Shengpai Huangxing engine oil in Hutu physical store;

1, due to excessive oil filling, the viscosity of the oil is not suitable and the carbon deposition is moderate.

2, adding inferior engine oil and other reasons.

It is also possible that the water temperature is too high, depending on whether the water thermometer is normal. If the noise is loud when idling, and the vehicle is idling at high speed, it is likely to clean the throttle, air intake and nozzle of the car.
