The method of issuing a certificate for self-use oil is as follows

The format is the same as the general certificate format. The content of the certificate must explain the use of the oil and the seal of the company, or the signature of the person, just to prevent some Criminals use gasoline to commit crimes.

If it is for your own use, keep a copy of your ID card and a certificate with your signature, the purpose of the gasoline, what happened, and a certificate that has nothing to do with the gas station.

If the company uses oil, you must also provide a certificate proving the purpose of the gasoline and that the accident has nothing to do with the gas station, and stamp it with the official seal of the company, and that's it.
