What Type of Fuel Should a China VI Standard Vehicle Use?
3 Answers
China VI models only refer to vehicles whose emissions of various pollutants meet the China VI limit requirements, and the type of fuel used is irrelevant. Simply follow the vehicle's manual for fuel recommendations. Below is relevant information about China VI standards: 1. Concept: The term 'China VI' means that a vehicle's emission standards meet the requirements specified in the sixth phase of the national emission standards, commonly abbreviated as China VI emissions. This standard began to be implemented gradually from the end of 2019. China's vehicle emission standards are modeled after European emission standards, with the latest being the China VI emission standard. The sixth phase imposes stricter regulations, significantly reducing the levels of various harmful gases. 2. Emission Standards: These regulations specify the permissible levels of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter. The purpose of setting vehicle emission standards is to curb the production of these harmful gases, encouraging automobile manufacturers to improve emission standards and reduce the generation of harmful gases.
I've been using 95-octane fuel for my China VI compliant car, even though the manual specifies a minimum requirement of 92-octane. The higher octane rating of 95 is more compatible with high-pressure fuel injection systems. With the increased precision of China VI engines, they're particularly sensitive to fuel quality. While lower-octane fuel might work, prolonged use can lead to carbon buildup and affect the lifespan of the particulate filter. Several friends who opted for cheaper 92-octane fuel had their exhaust system warning lights come on at just 20,000 kilometers. Gas station attendants often say '92 is enough,' but I take that with a grain of salt—I always double-check the pump to confirm it's 95 before fueling up.
After 20 years in auto repair, I've found that fueling errors in China VI vehicles are particularly common. The key is to check the fuel cap label. Most China VI vehicles require gasoline with an octane rating of 92 or above, but I strongly recommend using 95 or 98 octane! This isn't just because of the high engine compression ratio, but more importantly because low-sulfur gasoline is essential for protecting the particulate filter. Last week, I repaired a vehicle whose catalytic converter was ruined due to long-term use of substandard fuel - the repair cost could've covered two years' worth of premium fuel. Remember, reputable gas stations are the way to go. Fuel from small, unregulated stations may exceed sulfur limits - don't risk damaging your beloved car to save a few bucks.
