What is the difference between non-standard diesel and national standard diesel?
4 Answers
The differences between non-standard diesel and national standard diesel are as follows: Color: Generally, high-quality diesel for vehicles should be a transparent liquid that is colorless, light yellow, or light brown, slightly transparent without any turbidity. For more oil-related information, oil product details, and oil blending techniques, you can follow the oil product circle. Diesel that appears black, dark, or soy sauce-colored is low-grade blended oil; diesel that appears turbid is inferior oil mixed with water or impurities. Odor: High-quality diesel has a normal oil smell; inferior diesel has a pungent odor, such as a strange smell or a spicy and unpleasant odor from recycled oil. Texture: High-quality diesel has a low viscosity to the touch; diesel that feels too thick is inferior diesel mixed with other lubricating oils.
I used to save money by using non-standard diesel, but then my car frequently had trouble starting. Later, I realized the difference. Non-standard diesel usually refers to non-compliant fuel with high sulfur content, which easily causes pollution. It’s cheaper but damages the engine. For daily drivers like me, using non-standard fuel might seem cost-effective, but in the long run, it can clog the fuel injectors and reduce power, leading to higher repair costs. Standard diesel, on the other hand, is much more reliable. It meets national environmental standards, has higher cleanliness, runs more smoothly, and offers more stable fuel consumption. I think it’s best to check the gas station’s signage when choosing fuel. Getting standard diesel from official channels protects your car and saves you money and hassle—don’t fall into the trap of cheap fuel.
From an environmental perspective, there is a significant difference between non-standard diesel and national standard diesel, which impacts air quality. I always pay attention to emission issues. Non-standard diesel contains a large amount of impurities and sulfur, and its combustion releases more harmful particulate matter, such as PM2.5, contributing significantly to urban smog. In contrast, national standard diesel strictly limits sulfur content, effectively reducing exhaust pollution. Using non-standard diesel not only harms the environment but may also violate regulations and result in fines. I recommend everyone use national standard diesel to foster good habits, protecting both health and ecological balance. A simple change can promote green transportation.
As someone who frequently repairs cars, I've found that non-standard diesel can easily cause engine problems. Standard fuel is cleaner with added antifreeze, while non-standard fuel has more sulfur and impurities that clog fuel lines, leading to carbon buildup and shortening component lifespan. Using standard fuel is worry-free and safer.
