Is China VI gasoline ethanol gasoline?
2 Answers
China VI gasoline is not necessarily ethanol gasoline; it could also be diesel or gasoline with other components, specifically referring to fuel products that meet the China VI emission standards. China VI refers to the emission standard, not a type of gasoline. It imposes limits on exhaust emission indicators based on comprehensive automotive technical conditions, with fuel being just one factor affecting emissions. The China VI Motor Vehicle Pollutant Emission Standards are established to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China, aiming to prevent and control pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.
I've just researched this matter. China VI gasoline is actually the national sixth-stage fuel standard, focusing on reducing emission pollution, such as exhaust gases and particulate matter, but it's not necessarily ethanol-blended gasoline. Ethanol gasoline is fuel mixed with ethanol, like E10 which contains 10% ethanol, primarily helping to reduce reliance on fossil fuels. China VI gasoline can be either regular unleaded or ethanol-blended, as long as it meets environmental standards, because the stricter requirements are on sulfur content and additive control. In China, some cities promote ethanol gasoline as a way to achieve the China VI standard—for example, Beijing offers E10—but this isn't universal; gas station pumps clearly label the type. When refueling my car, I always pay attention to the distinction, as pure gasoline may be more engine-friendly for older vehicles and offers better fuel efficiency. I recommend everyone check the labels when filling up.
