What is the National Standard for Automotive Gasoline?

[DelFelix]

It will help promote the overall improvement of the quality of automotive gasoline in China, reduce the emission of pollutants from motor vehicles, and reduce the emission of nitrogen oxides and particulate matter from new vehicles by 25% and 80% respectively, while the emission of in-use vehicles can be reduced by 10-15% overall. The following is the relevant introduction: Implementation: It stipulates the terms and definitions, product classification, requirements and test methods, sampling, labeling, packaging, transportation and storage safety of automotive gasoline, as well as the implementation of the standard. Improvement: This standard applies to automotive gasoline used in spark-ignition engines, obtained from petroleum or with additives to improve performance.

As someone who has long been concerned about environmental protection, I have deep feelings about the national standards for automotive gasoline. The national standards mainly refer to GB17930, requiring ultra-low sulfur content in gasoline, which is now unleaded, with sulfur content reduced to below 10ppm. This is particularly important for reducing vehicle exhaust emissions, protecting air quality, and mitigating smog issues. From National V to National VI, the standards have become increasingly stringent, also limiting harmful components such as benzene and olefins to ensure cleaner gasoline. The benefit is that our vehicle exhaust pollution is reduced when driving, and it works more efficiently with exhaust treatment systems. Some people think that higher-octane gasoline is more environmentally friendly, but in fact, it is not directly related to the octane rating; the key is whether the components meet the standards. I recommend choosing reputable major brands when refueling to avoid potential adulteration at small gas stations, ensuring that your car runs greener, is more environmentally friendly, and contributes to healthier living for everyone.

As an average driver, my main concern when refueling is the fuel standards. China's gasoline national standards specify grades like 90, 92, 95, and 98, which represent the octane rating—the higher the octane number, the better the anti-knock performance. However, higher octane doesn't necessarily suit all cars; you should always check your vehicle's manual for the recommended grade. The standards also require low sulfur content and lead-free formulations to prevent engine and catalytic converter corrosion, thereby extending the vehicle's lifespan. The benefits are cost savings and peace of mind, as compliant gasoline has better cleaning properties, reduces carbon buildup, and ensures smoother driving. Some people mistakenly believe that higher octane means more power, but it actually depends on the car's design—using the wrong grade might even increase fuel consumption. I usually opt for 92-octane, following the recommended standard, which keeps my car protected and worry-free. When refueling, always look for the compliance mark to avoid being tricked by cheap counterfeit products.

I'm a veteran driver with 30 years of experience, having witnessed the evolution of gasoline standards. We used to use leaded gasoline, but now the national standard has shifted to unleaded and low-sulfur fuel, with clear octane ratings to prevent engine knock damage. From National I to National VI upgrades, emission restrictions have become stricter, resulting in benefits like reduced vehicle noise, stable power output, and fewer fuel system clogs. Some people forget to check manufacturer recommendations and waste money by arbitrarily using higher octane fuel. I always verify standard compliance when refueling.
