National III diesel for National V diesel vehicles
Thread Content
Can National V diesel vehicles use National III diesel? In terms of specifications, the difference between National V, National IV, National III diesel fuels lies solely in their sulfur content. So, can vehicles meeting National Standard 5 use National Standard 3 diesel? Will long-term use have any effects?

There is definitely some impact; high sulfur content can cause cylinders to corrode, resulting in emissions that do not meet standards! ! ! !
Can it be driven normally? Excluding engine corrosion and exhaust emissions, could it make the car more prone to breakdowns? For example, a clogged fuel injector that prevents the engine from starting, or a car that lacks power?
I’ll take care of it myself. I need a solution. . . .
National III, National IV, and National V refer to emission standards; the requirements for engines are the same in these standards. Vehicles meeting National V standard are equipped with urea-based denitration systems, while those meeting National III standard do not have such after-treatment systems. Fuel suitable for National III standard has little impact on the engine; what matters is that the emissions do not meet the specified standards
Correct answer. There is no evidence available indicating that diesel meeting National III standards has a high sulfur content that causes cylinder corrosion; the improvement in diesel quality is entirely driven by environmental protection requirements.
The impact on the vehicle itself shouldn’t be very significant; it’s just due to environmental regulations
