Can China VI Vehicles Use Non-Standard Diesel?

[EvanLynn]

China VI vehicles cannot use non-standard diesel. Reasons why China VI vehicles cannot use non-standard diesel: To meet emission standards, China VI engines have undergone optimizations in many core components. In principle, China VI trucks must use China VI diesel. The so-called "non-standard diesel" contains relatively more impurities, which can shorten the service life of diesel filters and may also cause premature damage to fuel injectors. Maintenance methods for China VI vehicles: The after-treatment systems of China VI vehicles are significantly different from those of China V vehicles. Older generation engine oils have higher viscosity and are suitable for previous-generation engines with larger gaps between piston rings and cylinder walls. In contrast, the new generation of China VI engines has higher precision, greater power, and higher operating temperatures. Engine oils specifically designed for China VI engines contain low-ash additives that can protect the exhaust after-treatment system while meeting the lubrication requirements of the engine. Therefore, China VI vehicle owners must take good care of the after-treatment system by choosing engine oils that meet the manufacturer's requirements.

Cars meeting China VI emission standards have particularly high requirements for gasoline quality. I've been driving such a car for three years, and using low-quality fuel can cause severe engine carbon buildup, with clogged fuel injectors being a common issue. Once I tried to save money by refueling at a small gas station, which resulted in severe engine shaking and the emission warning light coming on. The repair revealed a damaged oxygen sensor, costing me 2,000 RMB to fix. I recommend only using Sinopec or PetroChina's 95-octane or higher gasoline to avoid impurities in low-quality fuel. China VI systems are equipped with DPF filters, which are prone to clogging with inferior fuel, increasing maintenance frequency and costs. From my experience, spending a little extra on proper fuel is far more economical than dealing with costly repairs.

As an average car owner, I once tried using lower-grade fuel to save money. At first, it seemed like a bargain with a few cents saved per liter, but after a few weeks, my car started experiencing sluggish acceleration and significantly increased fuel consumption. The mechanic diagnosed it as fuel pump and filter corrosion caused by impurities, which was both troublesome and costly to fix. With the precision engineering of China VI emission standard vehicles, substandard fuel can easily compromise overall performance—definitely not worth the trade-off. Now I only refuel at major gas stations, and my car runs much smoother, giving me peace of mind and prolonging its lifespan. Here's food for thought: the short-term benefits of inferior fuel lead to long-term issues—it's simply not worth it.

From an environmental perspective, I support the China VI emission standards to reduce exhaust pollution, but using substandard fuel can backfire. Low-quality gasoline with high sulfur content leads to excessive emissions, damages the catalytic converter, and worsens air pollution. I've seen a neighbor's car get fined for such practices. Consistently using qualified fuel not only protects your vehicle but also contributes to green transportation.
