It is recommended to avoid small gas stations whenever possible and opt for larger ones to ensure fuel quality cannot be guaranteed at smaller stations. Here are some relevant details about China V vehicles: Purpose of China V: China V vehicles refer to emission standards set by the national government for different stages, primarily aimed at controlling and reducing vehicle pollutant emissions. The later the stage, the more energy-saving and emission-reducing it becomes. The national standard for Stage V vehicle gasoline was issued by the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration of China on December 18, 2013. China VI Fuel: Compared to China V standard gasoline and diesel, China VI fuel reduces carbon monoxide emissions by 50%, total hydrocarbon and non-methane hydrocarbon emission limits by 50%, and nitrogen oxide emissions by 42%. Moreover, China VI fuel contains fewer harmful components than China V, effectively reducing engine carbon deposits and significantly lowering damage to vehicles and machinery.

As an ordinary person who has driven a China V diesel vehicle for ten years, I once tried saving money by using low-quality fuel. After just a week, the engine started shaking abnormally and the warning light came on. Upon inspection, it was found that the fuel injectors were clogged, costing over 2,000 yuan in repairs. Low-quality fuel contains more impurities and higher sulfur content – saving a few bucks short-term but destroying precision components long-term. The emission system of China V vehicles relies on clean diesel to maintain DPF functionality, and using inferior fuel accelerates part corrosion and causes emission exceedances. Now I insist on using standard fuel—though more expensive, it protects vehicle longevity and reduces malfunctions. Calculating the total cost actually saves money in the long run. I advise owners not to take risks and to develop good habits.

From an environmental perspective, I strongly believe that using substandard fuel for China V diesel vehicles is absolutely unacceptable. These non-compliant fuels contain excessively high sulfur levels, releasing more pollutants during combustion and harming the environment. The China V emission standard was specifically designed to reduce pollution, but inferior fuel can damage catalytic converters or DPFs, causing exhaust emissions to exceed limits and defeating the original environmental purpose. Having participated in air quality initiatives, I've witnessed numerous cases that serve as warnings for social responsibility. Using such fuel not only wastes resources but also poses health risks. It's far better to choose compliant diesel – benefiting both society and individuals while promoting sustainability. Environmental protection starts with daily actions, and change begins with every drop of fuel.

Having worked in the auto repair industry for years, I've seen countless troubles caused by owners of China V standard vehicles using low-quality fuel. Issues like impurities clogging fuel lines and wearing out fuel injectors are commonplace, often leading to DPF blockages with repair costs running into thousands. Those cheap fuels save little money but cause engines to fail prematurely. High-quality equipment demands premium fuel for stable operation, making regular part replacements more cost-effective. I always advise customers to stick to diesel from authorized channels—fewer vehicle issues and longer service life.
