Does Using China 6 Engine Oil in a China 5 Vehicle Have Any Impact?

[DeRylee]

Using China 6 engine oil in a China 5 vehicle has no negative impact. China 6 fuel contains lower levels of harmful substances, effectively reducing engine carbon buildup and minimizing engine wear. As a result, the vehicle's power performance and driving smoothness will improve, while fuel consumption levels will decrease. Below is a comparison between China 5 and China 6 standards: 1. Emission Standards: China 6 emission standards impose stricter limits compared to China 5, with additional regulations on PN (particulate number) emissions; 2. Light-duty Gasoline Vehicles: Under China 6 standards, certain emissions from light-duty gasoline vehicles will be reduced by approximately 50% compared to China 5, with particulate emissions decreasing by about 40%; 3. Heavy-duty Diesel Vehicles: For heavy-duty diesel vehicles, nitrogen oxides and particulates under China 6 will be lower than those under China 5.
