Can China VI Vehicles Use Non-Standard Fuel?
2 Answers
China VI vehicles cannot use non-standard fuel. Here is relevant information: Advantages of China VI standard vehicles: "China VIa" is essentially a transitional phase between "China V" and "China VI", while "China VIb" represents the true "China VI" emission standard. Without considering the impact of test conditions and procedures, compared to the "China V" emission standard limits, the CO limit for China VIa gasoline vehicles is 50% stricter. China VI vehicles are equipped with additional components compared to China V vehicles. Additionally, automakers incur extra costs from vehicle certification announcements, various tests, and production, resulting in significantly higher prices for China VI vehicles compared to China V vehicles. China VI-compliant models: Currently, there are several hundred models that meet the China VI standard. The three major luxury brands—BMW, Mercedes-Benz, and Audi—have largely completed their upgrades to the China VI standard. Popular models from Volkswagen, Toyota, Honda, Nissan, and others have also mostly been upgraded. Some of the more popular models include the Acura RDX, Volvo XC60, Infiniti QX50, Cadillac XT4, and Camry. Domestic brands such as the new-generation Roewe RX5, Changan, and Yidong also comply with the China VI standard.
I've done extensive research on why China VI vehicles can't use non-standard fuel. To meet the strict China VI emission standards, these engines are equipped with GPF particulate filters and advanced fuel injection systems. The fuel quality at small stations varies greatly, often with high sulfur content and impurities, which can clog fuel injectors or corrode the catalytic converter. Last year, I saw a friend's China VI car constantly triggering emission warning lights due to long-term use of substandard fuel, eventually requiring a 6,000+ yuan catalytic converter overhaul. This not only reduces vehicle lifespan but also causes drastic fuel consumption increases. Therefore, I recommend owners choose official Sinopec or PetroChina stations, use the recommended octane rating (like 95#), and perform regular fuel system cleaning to avoid major repairs. Trying to save small money often leads to bigger expenses - safety should always come first.
