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.
