Owing to the drive for more fuel-efficient, lighter, and smaller engines with longer lifetime for modern automobiles and machines that can operate in extreme conditions, engine lubricants have to meet increasingly stringent requirements to match the high demands and to offer tangible performance and economic benefits. Synthetic lubricants, formulated from synthetic base stocks of uniform and well-defined molecular structures, have shown outstanding performance advantages compared to conventional lubricants based on mineral base oils from petroleum, which have undesired complex compositions and broad distributed performance properties. Owing to the severe competition from other base stocks and increasing market demands on lubricant performance, the synthetic lubricant industry is driven to develop and market next-generation, high-performance synthetic base stock technologies to remain competitive in the global market.
