Polyalphaolefins, often abbreviated as PAOs, are a family of synthetic base oils widely used in the formulation of high-performance lubricants. They are derived from alpha-olefins, which are unsaturated hydrocarbons. The polymerization process typically involves oligomerization of 1-decene, although other alpha-olefins like 1-octene and 1-dodecene can also be used.

The primary advantage of PAOs lies in their superior physical properties compared to conventional mineral oils. They exhibit excellent low-temperature fluidity, meaning they remain pourable and effective at very cold temperatures, which is crucial for applications like automotive engine oils. Conversely, PAOs also possess high viscosity indices, indicating that their viscosity changes less with temperature fluctuations, providing consistent lubrication across a broad operating range.

Furthermore, PAOs demonstrate good thermal and oxidative stability. This resistance to breakdown at high temperatures and in the presence of oxygen leads to longer lubricant life and reduced deposit formation in engines and machinery. Their low volatility also contributes to reduced oil consumption.

Due to these advantageous characteristics, PAOs are extensively employed in demanding applications such as synthetic engine oils for passenger cars and heavy-duty trucks, gear oils, hydraulic fluids, compressor oils, and greases. They are often blended with other base oils or additive packages to achieve specific performance requirements for a wide array of industrial and automotive uses.
