Has anyone used the group oil App under the energy chain? how

I have used the group friend App, which is quite reliable. The group friend App covers the digital refueling network of about 1 1,800 towns across the country. It is especially convenient to refuel when traveling outside. You can see many gas stations nearby, as well as address, oil number, oil price and other information, and the quality of their oil products is also greatly guaranteed. Group members and PICC China have introduced product liability insurance and refueling insurance. If you encounter oil quality problems at an insurance-certified gas station, the quality inspection agency can get the highest quality after testing and confirmation.
