Base Oil SN 350 is a medium stock base oil produced from the vacuum distillates and residual components using the traditional refining methods. It has viscosity 8-9,5 cSt at 100C and 67-70 cSt at 40C. SN 350 is used in lubricant and lubricant additives production, mainly for industrial applications. The main benefits of SN 350 base oils are low sulphur content, high viscosity index, high oxidation stability and good susceptibility to the additives.
