Is the quality of Meifu petroleum products poor?

Meifu petroleum products are of good quality.

Petroleum refers to the mixture of natural gaseous, liquid and solid hydrocarbons. Petroleum is divided into crude oil, natural gas, natural gas liquid and natural tar, but it is customary to use "oil" as the definition of "crude oil".

Petroleum is a thick dark brown liquid, which is called "industrial blood". There are oil reserves in some parts of the upper crust. The main components are mixtures of alkanes, cycloalkanes and aromatic hydrocarbons. It is one of the main targets of geological exploration.

There are two theories about the mechanism of petroleum formation: biological deposition and petrochemical formation. The former is widely accepted that oil is formed by the long evolution of organisms in ancient oceans or lakes, which belongs to biological deposition and cannot be regenerated. The latter thinks that oil is generated by carbon in the earth's crust, which has nothing to do with living things and is renewable. Petroleum is mainly used as fuel oil and gasoline, and it is also the raw material of many chemical industrial products, such as solutions, fertilizers, pesticides and plastics.
