Base Oil – SOC-4

SOC-4, supplied by Maccoran Petroleum Company, is a paraffinic base oil with a very high viscosity index (VHVI). The high quality of this product is the result of using selected feed and additional refining processes. This base oil produces many lubricants, including gasoline and diesel engine oils, gears, turbines, hydraulics, compressors, and other industrial oils. According to the API classification, the low amount of sulfur, the high percentage of saturated compounds, and the high viscosity index value of 120 make this oil one of the group (III) oils. This oil is sold in bulk, barrel, Flexi, and IBC packages.
