4. PAO (Polyalpha olefin)

Polyaolefin is a type of synthetic base oil. Poly alpha olefin (PAO) is produced by polymerizing ethylene to produce alpha olefin, which is then further polymerized and hydrogenated. It is the most commonly used synthetic lubricant base oil and has the widest range of applications. Poly (alpha olefin) synthetic oil (PAO) has good viscosity temperature performance and low-temperature flowability, making it an ideal base oil for formulating high-end and specialized lubricants.
