Euro-4 Gasoline in All Big Cities

Gasoline sold in big cities is compliant with Euro-4 emission standards, an official at the National Iranian Oil Products Distribution Company said.
According to Fatemeh Kahi, a study recently conducted by the Iranian National Standards Organization from Sept. to Dec. 2020 on gasoline quality indicates the fuel contains acceptable levels of sulfur and other chemicals, IRNA reported.
“Not only have sulfur levels declined compared to summer, aromatic compounds, benzene, octane and olefin also are at acceptable levels.” 
As part of the study, samples of gasoline compliant with Euro-4 emission standards were collected randomly from 200 gas stations and the results revealed that sulfur and aromatic hydrocarbon levels were admissible, she said.
