　　Comparative Analysis of Vehicle Gasoline Standards in the US, Europe, and Japan By comparing the changes in the key parameters of vehicle gasoline standards in these regions over the years, it can be seen that, in the long term, the sulfur content, olefin content, aromatic content, and benzene content in gasoline all show a downward trend, although the rate of this decline varies. Gasoline sulfur content is decreasing the fastest ； The requirements for benzene content are quite strict, with minimal variations ； The olefin content remains relatively constant ； The aromatic content has decreased, but at a relatively slow pace. In terms of specific indicators, there are clear differences among the three. Why is there such a significant difference? Below is a comparative analysis of the sulfur content, olefin content, aromatic content, benzene content, and octane rating of gasoline. 　　Table 1 Comparison of gasoline standards in the US, EU, and Japan.
