Base Oil Group – IV

PAO 2cSt

Description:
PAO 2 is a synthetic hydrocarbon base oil belonging to the Group IV classification under API guidelines. It is produced via the oligomerization of alpha-olefins, typically 1-decene, followed by hydrogenation. With a kinematic viscosity of ~2 cSt at 100°C, PAO 2 offers excellent thermal stability, oxidation resistance, and low volatility, making it ideal for applications requiring low-viscosity, high-performance lubrication.

Thanks to its outstanding low-temperature fluidity and shear stability, PAO 2 is often used in formulations where fuel economy, cold-start performance, and extended oil life are critical.

Key Performance Features:

• Excellent oxidation and thermal stability

• Very low pour point for enhanced low-temperature performance

• Low volatility – reduces oil consumption and emissions

• High viscosity index – maintains consistent viscosity across temperature extremes

• Fully compatible with Group III, IV, V base oils and most additive systems

• Non-toxic, colorless, and odorless

Applications:

• Fuel-efficient engine oils (PCMO and HDEO)

• Electric vehicle (EV) fluids

• Compressor and turbine oils

• Hydraulic fluids requiring low start-up viscosity

• Grease manufacturing (as synthetic base)

• Industrial lubricants where shear stability is essential
