Sinopec, as one of the largest oil and chemical companies in China, offers a wide range of products and services, including oil refining, petrochemicals, natural gas and pipelines, as well as refined oil sales. For consumers looking to purchase 40 liters of gasoline or diesel at a Sinopec gas station, here are the general procedures to follow:

Firstly, drive to the Sinopec gas station and select the appropriate fuel dispenser. Sinopec stations typically have various types of dispensers, including diesel and gasoline dispensers, and consumers should choose the one that suits their vehicle's needs.

Next, insert the fuel nozzle into the fuel tank and choose the desired fueling method, such as fixed volume fueling or self-service fueling. If opting for fixed volume fueling, inform the attendant of the desired fuel volume, such as 40 liters. For self-service fueling, consumers can set the fuel volume through buttons or a touch screen on the dispenser.

During the fueling process, consumers should remain vigilant, ensuring a tight connection between the fuel nozzle and the fuel tank to prevent fuel leakage. It's also important to monitor the metering device on the dispenser to ensure the correct fuel volume and amount.

Finally, once fueling is complete, remove the fuel nozzle and securely close the fuel tank cap. Then, proceed to the cash register inside the gas station to pay for the fuel. Sinopec stations typically accept various payment methods, including cash, bank cards, and mobile payments. Upon payment, consumers will receive a receipt and can depart from the gas station.

These are the basic procedures for purchasing 40 liters of gasoline or diesel at a Sinopec gas station. By following these steps, consumers can complete the fueling process conveniently and safely.
