Are China V and China VI fuels the same?

[ODominic]

China V and China VI fuels are not the same. For most vehicle models, China VI standards result in slightly higher fuel consumption compared to China V. Here are the reasons: 1. China VI emission standards are much stricter than China V: This requires installing more powerful filtration systems in the three-way catalytic converter. While stronger filtration systems effectively reduce pollutant emissions, the denser filtration system undoubtedly significantly impacts exhaust efficiency, potentially causing poor engine exhaust and increasing fuel consumption to some extent. 2. Changes in manufacturer strategies: Many automakers also adopt strategies such as reducing vehicle power, modifying fuel injection programs, or even switching from four-cylinder to three-cylinder and six-cylinder to four-cylinder engines to meet the stringent China VI standards. These modifications undoubtedly have a considerable impact on performance.
