This clearly shows that a PAO base oil substitution can significantly lower operating temperatures of the gear box and extend the required maintenance interval. Both basestock types have low volatility and high fire points (when stabilized) for a given viscosity grade. Note the differences between a VHVI mineral oil and Synfluid Polyalphaolefin (PAO) 5 in the Scanning Brookfield chart below. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. They may also be used in applications and areas that may result in incidental food contact or on equipment where there is a potential exposure of the lubricated part to food, such as on food processing equipment as a protective anti-rust film. For example, one would not be able to make an 0W-20 oil with a C12-derived PAO as the viscosities are too high. The superior low-temperature flow characteristics of PAOs ensure faster coating of critical parts in the compressor during startup, minimizing wear. However, PAOs can help. Chemical kinetics tell us that if you reduce the temperature, you will reduce the reaction rate. Furthermore, the process is a simpler, more energy-efficient route for grease production. Polyolefins, including poly (ethylene), poly (-olefin), poly (styrene), and poly (dienes), are the most widely-used polymer materials. However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. It is possible to get added property benefits from C12-based Synfluid PAOs. However, Group III base stocks are derived from multiple feedstock choices and processing technologies, which create variability in the properties. Metallocene-catalyzed commercial mPAO basestock grades can attain a viscosity of 300 cSt at 100C. One example is the advantage PAO has over mineral oil in the area of high-temperature stability.
