In terms of viscosity, there are tradeoffs in choosing one PAO over another: energy consumption (heat dissipation and production throughput) versus safety of operations (impacted by flash/fire points and volatility). For instance, a 100 percent aminic antioxidant package will yield the best performance in the Rbot test for PAO. PAO fluids are classified as a Group IV base oil and are made by a two-step reaction process using linear alpha-olefins like 1-decene. Low-temperature fluidity and high-temperature thermal and oxidative stability are key factors for choosing a PAO. 0000004340 00000 n This clearly shows that a PAO base oil substitution can significantly lower operating temperatures of the gear box and extend the required maintenance interval. After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. Due to this incompatibility with many but not all PAG lubricants, system change-outs from mineral oil to PAG-based lubricants may be costlier and take additional time. 56 0 obj<>stream Why does this happen?
