Are the prohibited substances in European gasoline standards the same as those tested in domestic gasoline?

Although both European and Chinese gasoline standards impose strict limits on the levels of harmful substances, the list of specific substances that are prohibited may differ. Since different countries or regions may prioritize different aspects such as environmental protection and health, the specific substances that are prohibited can vary. Taking the example you mentioned, Europe’s fuel standard EN 228 does not explicitly prohibit the presence of methyl acetals, anilines, and esters; however, it sets strict limits on the levels of toxic elements such as sulfur and lead. China’s GB 17930-2016 \"Petroleum-based liquid fuels for gasoline and diesel\" specifies limits for various harmful substances, including formaldehyde and anilines, and also sets limits on toxic elements such as sulfur and lead. Therefore, to clearly compare the differences between the two, it is necessary to carefully examine and compare the specific regulations and standards in China and Europe. It is recommended that you consult relevant professionals or institutions for more accurate information. .

You can check China’s standards for gasoline used in vehicles, as well as Europe’s standards for gasoline used in vehicles. The national standards for vehicle gasoline can be found online; I’m not sure about those in Europe. In my personal opinion, under Europe’s standards for automotive gasoline, there are probably no particular restrictions on those so-called prohibited substances; after all, their prices in Europe are quite high, and adding them to automotive gasoline would make the cost structure unfavorable. But in China, there are indeed those containing carbonates, but the possibility of them containing aniline is almost non-existent, as aniline is much more expensive than gasoline. As for methyl acetal, generally that’s not an option either; using too little of it isn’t worthwhile, while using a bit too much results in a significant decrease in calorific value, which would greatly affect the business at gas stations. It would be even worse if they got sued as well.

Thank you to my senior for their generous guidance. Over the years, they have shown great knowledge and humility, always willing to help others – truly admirable! Impressive!

I’m very grateful to you for answering my questions. The system failed to display your reply in time yesterday, so I saw it a bit late. GBT33648 specifies typical unconventional additives, which is quite clear. I will consult with professionals to see if the EU has any similar standards or regulations regarding typical unconventional additives. Thank you again!
