The second category of mineral oil hydrocracking, hydrotreating by oil fractionation, more refined and purified. The third height hydroisomerization hydrocracking or synthetic wax, the second type is a more highly hydrocracking base oil production, or synthetic wax hydroisomerization, (a byproduct of the dewaxing process). The fourth category is synthetic poly-α-olefins (PAOs), is by α- olefin oligomerization catalyst role by hydrogenation of unsaturated and production. The fifth class is an all-encompassing synthetic minerals, the fifth base oils include polyol esters, polyalkylene glycols Xing base (polyalkylene glycols (PAG)) and perfluoropolyalkylethers (PFPAEs). Use the power of clean technologies to protect Stockman FX-SC power clean oil using special techniques to make the engine to achieve higher operating efficiency of oil, so that the drive smoother and more quiet.
