4cSt VHVI Synthetic Base Oil
ZMPC
pao 4cSt VHVI
As lubricant manufacturers continue to pursue higher efficiency, lower emissions, and longer drain intervals, Group III+ base oils have become the preferred choice for modern synthetic lubricant production.
Our 4cSt VHVI Synthetic Base Oil is produced through advanced severe hydrocracking and hydroisomerization technology, delivering high purity, excellent oxidation resistance, and consistent molecular structure.
Compared with conventional mineral oils, this base stock provides improved thermal stability, cleaner operation, and enhanced formulation flexibility. Compared with traditional PAO4, it offers a highly attractive cost-performance balance for many automotive and industrial lubricant applications.
Precisely matched 3.714 cSt @100°C, allowing formulators to optimize synthetic lubricant blends while maintaining desired viscosity characteristics.
An economical alternative for synthetic lubricant blending, helping manufacturers reduce raw material costs while maintaining excellent overall lubricant performance.
Saturates: 99.8%
Sulfur: <0.0017 mg/kg
Acid Number: <0.01
Color: <0.5
