How about the oil of Golden Shield?

1. Reliable oil source: except Huangdao Refinery, it is mainly customized by Haike Refining and Chemical Company, without a drop of blended oil or inferior oil.

2. The oil index is much higher than the national V standard: the sulfur content and colloid are relatively low, which plays an important role in protecting the environment and reducing smog.

3. High cost performance: Compared with Sinopec and PetroChina, the oil quality of Jindun Gas Station is moderate and the price is relatively cheap.
