Viscosity index improver is designed to reduce the viscosity change of lubricating oil caused by temperature change. As a key component of engine oil, the choice of viscosity index improver is an important factor in the preparation of high quality engine oil.

Heavy duty engine oil additives are designed to meet the area specific needs of heavy truck transportation, mining and construction equipment.

We understand the operational challenges of our customers and the quality of heavy engine oil they value. This provides us with guidance for the selection of cost-effective and efficient multi-purpose additives.
With our extensive knowledge of how truck drivers, fleet operators, mining companies and construction companies operate, as well as close cooperation with major enterprise additive manufacturers, we develop high-performance heavy-duty engine oils.

We have done more than that. We have also developed a series of products with higher performance, which can extend the service life of engine and reduce the total operating cost compared with standard oil. So you can help consumers reduce engine wear, resist oil dilution, improve fuel economy, maintain power, and reduce sediment formation and filter plugging. Our new product line can meet your users' various operation and strict requirements.
