PAO-based lubricants offer a significant advantage in oxidative stability. PAOs are considered a very pure substance since they are derived from petrochemically pure ethylene and then from 1-decene or 1-dodecene, which could be considered a further purification step. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. If a certain application can sacrifice a 10 15C increase in the pour point, then there is as much as a 25% improvement in volatility, as shown in the chart below. xref This process creates a polymer backbone where oxygen is every third atom, which gives PAG basestocks their distinctive chemical attributes and allows formulators to synthesize various combinations of starters and monomers (block, random, and homopolymer) to create custom basestock types for specific applications. To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. In contrast, a mineral oil will require various antioxidants depending upon the structural makeup. To help you optimize your application, Chevron Phillips Chemical offers a wide variety of PAOs delivering oxidative and thermal stability advantages. Changes in low-temperature viscometrics and oxidative stability requirements demand higher-quality base oils. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. In addition to the low temperature performance demonstrated by CCS, the volatility and viscosity index of the PAO 5 and 7 blend are improved over traditional PAO 6. Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. You see, the jump hurts the pump.. 0000013783 00000 n When you add up the benefits, you may see that one plus one can make more than two. Synfluid PAOs are crafted from an on-purpose process that yields a consistent, high-quality product. A drop-in replacement for petroleum, it's used in countless applications in many industries. As oil volatilizes, the viscosity increase will result in poorer overall performance.
