  3. Why does the price difference exist in different crude oil transactions? Will this spread be unlimited? "> different crude oils do have price differences in the spot market. First of all, because the quality differences (proportion, sulfur content and other indicators) between different types of oil are relatively large, the price of light crude oil with low sulfur content is generally high, while that of heavy crude oil with high sulfur content is relatively low. Secondly, the quality of crude oil produced in different stages of the same oil will be different. Third, changes in supply and demand will also lead to changes in price differentials. For example, a fire shutdown of a refinery dedicated to a certain type of crude oil will often lead to a reduction in the price of the crude oil relative to other types of oil. Fourth, the price of the same oil will be different in different regions, so there will be regional price differences for the same oil.
