How To Choose a More Suitable Diesel Engine Oil?

In the era of China VI emission standards, environmental regulations are becoming increasingly stringent. Commercial vehicle owners are switching to China VI models, which brings new maintenance requirements. Therefore, choosing the right diesel engine oil becomes particularly important.


Differences Between Commercial Vehicle Models Compliant With China Vi Emission Standards And Previous Models

How To Choose a More Suitable Diesel Engine Oil?

The China VI emission standard has seen significant improvements compared to the China V standard, mainly reflected in the following aspects:

1. Improvement in emission control technology: China VI vehicles generally adopt more advanced emission control technologies, such as selective catalytic reduction (SCR) systems and diesel particulate filters (DPF). These technologies can effectively reduce emissions of nitrogen oxides (NOx) and particulate matter.

2. Engine design optimization: To meet stricter emission standards, the engine design of China VI vehicles has been optimized, incorporating higher combustion efficiency and a more precise fuel injection system. This has led to changes in engine operating conditions, such as higher temperatures and pressures.

3. Changes in lubricant demand: Due to the reduction in carbon deposits generated during the operation of China VI engines, new requirements have been imposed on the viscosity and ash content of lubricants. Diesel engine oils with low viscosity and low ash content are better suited to these new technologies.
