According to the actual vehicle test data provided by the China Automotive Technology Research Center, after using National VI B gasoline, the particulate matter emissions of gasoline vehicles can be reduced by 20% to 30%, hydrocarbons by 10% to 15%, and carbon monoxide by 6% to 10%.

The National VI B standard puts forward higher requirements for gasoline quality, and its main reference indicator is the emission data after gasoline combustion. Compared with the previous standard, the olefin content of National VI B gasoline has been reduced from 18% to 15%, resulting in better oil performance and higher quality. The reduction of olefin content in oil products can further reduce air pollution and effectively reduce engine carbon and gum deposition, thereby extending the service life of the engine.

It should be noted that the specific test data may vary due to factors such as testing methods, vehicle types, and driving conditions. If you want to learn more detailed and accurate data, it is recommended to refer to the testing reports of relevant professional organizations or automobile manufacturers.
