Oil extracted and processed from petroleum is called refined oil.

Crude oil (natural oil) is mined from underground and is called crude oil without processing.

In 2006, the state made it clear that the price of domestic refined oil was indirectly linked to the price of crude oil in the international market in a controlled way. However, due to the sharp rise in oil prices in the international market, this mechanism has not been fully implemented, and domestic refined oil prices and international crude oil prices have been upside down several times, especially in the first nine months of this year. While the oil price in the international market is falling and the fuel tax reform is advancing, it is necessary to improve the formation mechanism of refined oil prices as soon as possible and rationalize the refined oil prices.
