Synfluid® PAO 4 cSt

Passenger car driving down a road with a mountain in the background.jpg

Synfluid® PAO 4 cSt is a low-viscosity synthetic base oil which excels at meeting critical performance criteria for equipment protection, efficiency and longevity. Synfluid® PAO 4 cSt is produced through the process of synthesizing oligomers from a pure normal alpha olefin feedstock of 1-decene. The usage of a pure feedstock yields a consistent and high-quality product.  

Designed to deliver exceptional performance across a wide temperature range, this synthetic base oil offers excellent oxidative and thermal stability, low volatility, and high viscosity indices, making it ideal for use in lubricants, coolants, hydraulic fluids, and other functional fluids in transportation and industrial applications.
