C12-derived PAOs also provide advantages with higher Viscosity Index (VI), better flash/fire points, and even lower cold crank simulated viscosities. Synthetic basestocks, more so than in mineral oil basestocks, are the primary contributor to most of the basic properties of the lubricant, including oil or water solubility, low-temperature fluidity, lubrication, volatility, ignitability, and seal and paint compatibility. Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance. To mitigate this effect, We recommend taking a look at Synfluid PAO 5 and PAO 7, due to their excellent Noack volatilities of 5.5% and 2.3%, respectively. PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. polyalphaolefin-based lubricants. In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil. Our C10-based products, commercialized in the 1970s, were the first in the market. Our C12-based grades further improve flash/fire points by as much as 10 percent over other commercial polyalphaolefins. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. Conversely, if you reduce the temperature, the reaction rate decreases and the oil lasts longer, providing better protection. As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points.
